HADOOP-16380. S3Guard to determine empty directory status for all non-root directories.
...
Contributed by Steve Loughran and Gabor Bota.
This
* Asks S3Guard to determine the empty directory status.
* Has S3A's root directory rm("/") command to always return false (as abfs does)
* Documents that object stores MAY do this
* Overloads ContractTestUtils.assertDeleted to let assertions declare that the source directory does not need to exist. This stops inconsistencies in directory listings failing a root test.
It avoids a recent regression (HADOOP-16279) where if there was a tombstone above the first element found in a directory listing, the directory would be considered empty, when in fact there were child entries. That could downgrade an rm(path, recursive) to a no-op, while also confusing rename(src, dest), as dest could be mistaken for an empty directory and so permit the copy above it, rather than reject it "destination path exists and is not empty".

Contributed by Steve Loughran

- 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.

HADOOP-16085. S3Guard: use object version or etags to protect against inconsistent read after replace/overwrite.
...
Contributed by Ben Roling.
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.

This is needed to fix up some confusion about caching of job.addCache() handling of S3A paths; all parent dirs -the files are downloaded by the NM without using the DTs of the user submitting the job. This means that when you submit jobs to an EC2 cluster with lower IAM permissions than the user, cached resources don't get downloaded and the job doesn't start.
Production code changes:
* S3AFileStatus Adds "true" to the superclass's encrypted flag during construction.
Tests
* Base AbstractContractOpenTest can control whether zero byte files created in tests are encrypted. Not done via an XML attribute, just a subclass point. Thoughts?
* Verify that the filecache considers paths to not have the permissions which trigger reduce-privilege downloads
* And extend ITestDelegatedMRJob to test a completely different bucket (open street map), to verify that cached resources do get their tokens picked up
Docs:
* Advise FS developers to say all files are encrypted. It's otherwise harmless and it'll stop other people seeing impossible to debug error messages on app launch.
