HADOOP-16490. Avoid/handle cached 404s during S3A file creation.
Contributed by Steve Loughran.

This patch avoids issuing any HEAD path request when creating a file with overwrite=true,
so 404s will not end up in the S3 load balancers unless someone calls getFileStatus/exists/isFile
in their own code.

The Hadoop FsShell CommandWithDestination class is modified to not register uncreated files
for deleteOnExit(), because that calls exists() and so can place the 404 in the cache, even
after S3A is patched to not do it itself.

Because S3Guard knows when a file should be present, it adds a special FileNotFound retry policy
independently configurable from other retry policies; it is also exponential, but with
different parameters. This is because every HEAD request will refresh any 404 cached in
the S3 Load Balancers. It's not enough to retry: we have to have a suitable gap between
attempts to (hopefully) ensure any cached entry wil be gone.

The options and values are:

fs.s3a.s3guard.consistency.retry.interval: 2s
fs.s3a.s3guard.consistency.retry.limit: 7

The S3A copy() method used during rename() raises a RemoteFileChangedException which is not caught
so not downgraded to false. Thus: when a rename is unrecoverable, this fact is propagated.

Copy operations without S3Guard lack the confidence that the file exists, so don't retry the same way:
it will fail fast with a different error message. However, because create(path, overwrite=false) no
longer does HEAD path, we can at least be confident that S3A itself is not creating those cached
404 markers.

Steve Loughran 511df1e837 HADOOP-16430. S3AFilesystem.delete to incrementally update s3guard with deletions
Contributed by Steve Loughran.

This overlaps the scanning for directory entries with batched calls to S3 DELETE and updates of the S3Guard tables.
It also uses S3Guard to list the files to delete, so find newly created files even when S3 listings are not use consistent.

For path which the client considers S3Guard to be authoritative, we also do a recursive LIST of the store and delete files; this is to find unindexed files and do guarantee that the delete(path, true) call really does delete everything underneath.

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".

HADOOP-16384: S3A: Avoid inconsistencies between DDB and S3.
Contributed by Steve Loughran

Contains

- 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-16266. Add more fine-grained processing time metrics to the RPC layer -follow-on patch.
This follow-on patch to HADOOP-16266 fixes up the problem where logs were being full of
stack traces because the timeout passed down to select was in nanos, whereas the API
expected millis.

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.
