- HADOOP-16397. Hadoop S3Guard Prune command to support a -tombstone option.
- HADOOP-16406. ITestDynamoDBMetadataStore.testProvisionTable times out intermittently
This patch doesn't fix the underlying problem but it
* changes some tests to clean up better
* does a lot more in logging operations in against DDB, if enabled
* adds an entry point to dump the state of the metastore and s3 tables (precursor to fsck)
* adds a purge entry point to help clean up after a test run has got a store into a mess
* s3guard prune command adds -tombstone option to only clear tombstones
The outcome is that tests should pass consistently and if problems occur we have better diagnostics.

This patch
* changes the default for the staging committer to append, as we get for the classic FileOutputFormat committer
* adds a check for the dest path being a file not a dir
* adds tests for this
* Changes AbstractCommitTerasortIT. to not use the simple parser, so fails if the file is present.

This makes the HttpException constructor protected rather than public, so it is possible
to implement custom subclasses of this exception -exceptions which will not be retried.

S3Guard will now track the etag of uploaded files and, if an S3
bucket is versioned, the object version.
You can then control how to react to a mismatch between the data
in the DynamoDB table and that in the store: warn, fail, or, when
using versions, return the original value.
This adds two new columns to the table: etag and version.
This is transparent to older S3A clients -but when such clients
add/update data to the S3Guard table, they will not add these values.
As a result, the etag/version checks will not work with files uploaded by older clients.
For a consistent experience, upgrade all clients to use the latest hadoop version.
Adding a protected-scope getter for the DistCpOptions, so that a subclass does
not need to save its own copy of the inputOptions supplied to its constructor,
if it wishes to override the createInputFileListing method with logic similar
to the original implementation, i.e. calling CopyListing#buildListing with a path and input options.

This is the first step for on-demand operations: things recognize when they are using on-demand tables,
as do the tests.
