HADOOP-19221. S3A: Unable to recover from failure of multipart block upload attempt (#6938)

Browse Source 
This is a major change which handles 400 error responses when uploading
large files from memory heap/buffer (or staging committer) and the remote S3
store returns a 500 response from a upload of a block in a multipart upload.

The SDK's own streaming code seems unable to fully replay the upload;
at attempts to but then blocks and the S3 store returns a 400 response

    "Your socket connection to the server was not read from or written to
     within the timeout period. Idle connections will be closed.
     (Service: S3, Status Code: 400...)"

There is an option to control whether or not the S3A client itself
attempts to retry on a 50x error other than 503 throttling events
(which are independently processed as before)

Option:  fs.s3a.retry.http.5xx.errors
Default: true

500 errors are very rare from standard AWS S3, which has a five nines
SLA. It may be more common against S3 Express which has lower
guarantees.

Third party stores have unknown guarantees, and the exception may
indicate a bad server configuration. Consider setting
fs.s3a.retry.http.5xx.errors to false when working with
such stores.

Signification Code changes:

There is now a custom set of implementations of
software.amazon.awssdk.http.ContentStreamProvidercontent in
the class org.apache.hadoop.fs.s3a.impl.UploadContentProviders.

These:

* Restart on failures
* Do not copy buffers/byte buffers into new private byte arrays,
  so avoid exacerbating memory problems..

There new IOStatistics for specific http error codes -these are collected
even when all recovery is performed within the SDK.
  
S3ABlockOutputStream has major changes, including handling of
Thread.interrupt() on the main thread, which now triggers and briefly
awaits cancellation of any ongoing uploads.

If the writing thread is interrupted in close(), it is mapped to
an InterruptedIOException. Applications like Hive and Spark must
catch these after cancelling a worker thread.

/**
* Upload files/parts directly via different buffering mechanisms:
* including memory and disk.
* <p>
* Key Features
* <ol>
* <li>Support single/multipart uploads</li>
* <li>Multiple buffering options</li>
* <li>Magic files are uploaded but not completed</li>
* <li>Implements {@link Abortable} API</li>
* <li>Doesn't implement {@link Syncable}; whether to ignore or reject calls is configurable</li>a
* <li>When multipart uploads are triggered, will queue blocks for asynchronous uploads</li>
* <li>Provides progress information to any supplied {@link Progressable} callback,
* during async uploads and in the {@link #close()} operation.</li>
* <li>If a {@link Progressable} passed in to the create() call implements
* {@link ProgressListener}, it will get detailed callbacks on internal events.
* Important: these may come from different threads.
* </li>
*
* If the stream is closed and no update has started, then the upload
* is instead done as a single PUT operation.
*
* Unstable: statistics and error handling might evolve.
*
* </ol>
* This class is best described as "complicated".
* <ol>
* <li>For "normal" files, data is buffered until either of:
* the limit of {@link #blockSize} is reached or the stream is closed.
* </li>
* <li>If if there are any problems call mukund</li>
* </ol>
* <p>
* The upload will not be completed until {@link #close()}, and
* then only if {@link PutTracker#outputImmediatelyVisible()} is true.
* <p>
* If less than a single block of data has been written before {@code close()}
* then it will uploaded as a single PUT (non-magic files), otherwise
* (larger files, magic files) a multipart upload is initiated and blocks
* uploaded as the data accrued reaches the block size.
* <p>
* The {@code close()} call blocks until all uploads have been completed.
* This may be a slow operation: progress callbacks are made during this
* process to reduce the risk of timeouts.
* <p>
* Syncable is declared as supported so the calls can be
* explicitly rejected.
* explicitly rejected if the filesystem is configured to do so.
* <p>

Setting the option `fs.s3a.retry.http.5xx.errors` to `false` stops the S3A client from treating
500 and other HTTP 5xx status codes other than 501 and 503 as errors to retry on.
With AWS S3 they are eventually recovered from.
On a third-party store they may be cause by other problems, such as:
* General service misconfiguration
* Running out of disk storage
* Storage Permissions
Disabling the S3A client's retrying of these errors ensures that failures happen faster;
the AWS SDK itself still makes a limited attempt to retry.

There's two main causes
1. A class listed there is not an implementation of the interface.
Fix: review the settings and correct as appropriate.
1. A class listed there does implement the interface, but it has been loaded in a different
classloader, so the JVM does not consider it to be an implementation.
Fix: learn the entire JVM classloader model and see if you can then debug it.
Tip: having both the AWS Shaded SDK and individual AWS SDK modules on your classpath
may be a cause of this.
If you see this and you are trying to use the S3A connector with Spark, then the cause can
be that the isolated classloader used to load Hive classes is interfering with the S3A
connector's dynamic loading of `software.amazon.awssdk` classes. To fix this, declare that
the classes in the aws SDK are loaded from the same classloader which instantiated
the S3A FileSystem instance:

```
## <a name="400_bad_request"></a> 400 Bad Request errors
S3 stores return HTTP status code 400 "Bad Request" when the client make a request which
the store considers invalid.
This is most commonly caused by signing errors: secrets, region, even confusion between public and private

There's two main causes
This is an obscure failure which was encountered as part of
[HADOOP-19221](https://issues.apache.org/jira/browse/HADOOP-19221) : an upload of part of a file could not
be succesfully retried after a failure was reported on the first attempt.
1. A class listed there is not an implementation of the interface.
Fix: review the settings and correct as appropriate.
1. A class listed there does implement the interface, but it has been loaded in a different
classloader, so the JVM does not consider it to be an implementation.
Fix: learn the entire JVM classloader model and see if you can then debug it.
Tip: having both the AWS Shaded SDK and individual AWS SDK modules on your classpath
may be a cause of this.
1. It was only encountered during uploading files via the Staging Committers
2. And is a regression in the V2 SDK.
3. This should have been addressed in the S3A connector.
If you see this and you are trying to use the S3A connector with Spark, then the cause can
be that the isolated classloader used to load Hive classes is interfering with the S3A
connector's dynamic loading of `software.amazon.awssdk` classes. To fix this, declare that
the classes in the aws SDK are loaded from the same classloader which instantiated
the S3A FileSystem instance:
* If it is encountered on a hadoop release with HADOOP-19221, then this is a regression -please report it.
* If it is encountered on a release without the fix, please upgrade.
It may be that the problem arises in the AWS SDK's "TransferManager", which is used for a
higher performance upload of data from the local fileystem. If this is the case. disable this feature:

## <a name="access_denied"></a> Access Denied
HTTP error codes 401 and 403 are mapped to `AccessDeniedException` in the S3A connector.
### "The security token included in the request is invalid"
You are trying to use session/temporary credentials and the session token
supplied is considered invalid.

## <a name="500_internal_error"></a> HTTP 500 status code "We encountered an internal error"
```
We encountered an internal error. Please try again.
(Service: S3, Status Code: 500, Request ID: <id>, Extended Request ID: <extended-id>)
```
The [status code 500](https://developer.mozilla.org/en-US/docs/Web/HTTP/Status/500) indicates
the S3 store has reported an internal problem.
When raised by Amazon S3, this is a rare sign of a problem within the S3 system
or another part of the cloud infrastructure on which it depends.
Retrying _should_ make it go away.
The 500 error is considered retryable by the AWS SDK, which will have already
tried it `fs.s3a.attempts.maximum` times before reaching the S3A client -which
will also retry.
The S3A client will attempt to retry on a 500 (or other 5xx error other than 501/503)
if the option `fs.s3a.retry.http.5xx.errors` is set to `true`.
This is the default.
```xml
<property>
<name>fs.s3a.retry.http.5xx.errors</name>
<value>true</value>
</property>
```
If encountered against a third party store (the lack of an extended request ID always implies this),
then it may be a permanent server-side failure.
* All HTTP status codes other than 503 (service unavailable) and 501 (unsupported) are
treated as 500 exceptions.
* The S3A Filesystem IOStatistics counts the number of 500 errors received.
## <a name="503 Throttling"></a> HTTP 503 status code "slow down" or 429 "Too Many Requests"
The [status code 503](https://developer.mozilla.org/en-US/docs/Web/HTTP/Status/503)
is returned by AWS S3 when the IO rate limit of the bucket is reached.
Google's cloud storage returns the response [429 Too Many Requests](https://developer.mozilla.org/en-US/docs/Web/HTTP/Status/429)
for the same situation.
The AWS S3 documentation [covers this and suggests mitigation strategies](https://repost.aws/knowledge-center/http-5xx-errors-s3).
Note that it can also be caused by throttling in the KMS bencryption subsystem if
SSE-KMS or DSSE-KMS is used to encrypt data.
Consult [performance - throttling](./performance.html#throttling) for details on throttling.
