HADOOP-19015. Increase fs.s3a.connection.maximum to 500 to minimize the risk of Timeout waiting for connection from the pool
Contributed By: Mukund Thakur
Adds a new option `fs.s3a.endpoint.fips` to switch the SDK client to use
FIPS endpoints, as an alternative to explicitly declaring them.
* The option is available as a path capability for probes.
* SDK v2 itself doesn't know that some regions don't have FIPS endpoints
* SDK only fails with endpoint + fips flag as a retried exception; wit this
change the S3A client should fail fast.
PR fails fast.
* Adds a new "connecting.md" doc; moves existing docs there and restructures.
* New Tests in ITestS3AEndpointRegion
bucket-info command support:
* added to list of path capabilities
* added -fips flag and test for explicit probe
* also now prints bucket region
* and removed some of the obsolete s3guard options
* updated docs

Differentiate from "EOF out of range/end of GET" from
"EOF channel problems" through
two different subclasses of EOFException and input streams to always
retry on http channel errors; out of range GET requests are not retried.
Currently an EOFException is always treated as a fail-fast call in read()
This allows for all existing external code catching EOFException to handle
both, but S3AInputStream to cleanly differentiate range errors (map to -1)
from channel errors (retry)
- HttpChannelEOFException is subclass of EOFException, so all code
which catches EOFException is still happy.
retry policy: connectivityFailure
- RangeNotSatisfiableEOFException is the subclass of EOFException
raised on 416 GET range errors.
retry policy: fail
- Method ErrorTranslation.maybeExtractChannelException() to create this
from shaded/unshaded NoHttpResponseException, using string match to
avoid classpath problems.
- And do this for SdkClientExceptions with OpenSSL error code WFOPENSSL0035.
We believe this is the OpenSSL equivalent.
- ErrorTranslation.maybeExtractIOException() to perform this translation as
appropriate.
S3AInputStream.reopen() code retries on EOF, except on
RangeNotSatisfiableEOFException,
which is converted to a -1 response to the caller
as is done historically.
S3AInputStream knows to handle these with
read(): HttpChannelEOFException: stream aborting close then retry
lazySeek(): Map RangeNotSatisfiableEOFException to -1, but do not map
any other EOFException class raised.
This means that
* out of range reads map to -1
* channel problems in reopen are retried
* channel problems in read() abort the failed http connection so it
isn't recycled
Tests for this using/abusing mocking.
Testing through actually raising 416 exceptions and verifying that
readFully(), char read() and vector reads are all good.
There is no attempt to recover within a readFully(); there's
a boolean constant switch to turn this on, but if anyone does
it a test will spin forever as the inner PositionedReadable.read(position, buffer, len)
downgrades all EOF exceptions to -1.
A new method would need to be added which controls whether to downgrade/rethrow
exceptions.
What does that mean? Possibly reduced resilience to non-retried failures
on the inner stream, even though more channel exceptions are retried on.

Move the org.apache.hadoop.{oncrpc, portmap} packages from the hadoop-nfs module
to the hadoop-common module.
This allows for use of the protocol beyond just NFS -including within HDFS itself.

The option fs.azure.footer.read.request.size sets the size of the footer to
read and cache; the default value of 524288 has been measured to
be good for most workloads running on parquet, ORC and similar file formats.

The TimelineConnector.class has a hardcoded 1 minute connection time out, what makes the TestTimelineClient to a long running test (~15:30 min).
Decrease the timeout to 10ms will speed up the test run (~56 sec).
