HADOOP-13786 TestStagingCommitter -> java 8 closures

HADOOP-13786 HADOOP-14531 lambda wrapper around all production s3 calls
* all invocations of s3 calls are wrapped where appropriate, either with
once() (which does the translation), retry() or retryUntranslated
* javadocs state retry policy; this is propagated to give callers an idea
of what retries already
* commit tests -> java 8 lambdas too
* test json serdeser in hadoop common
* checkstyle

HADOOP-13786 HADOOP-14531
* new @Retries annotation for the s3a classes to use to make their retry
policy more visible in the source. This is a source-only annotation unused
anywhere, but does make visible policy. You can't call a non-retrying method
and be retrying yourself unless you add your own retry logic
* fault injecting AWSS3 client better about knowing when is good to fail
(i.e not so aggressively on listing operations)
* callback interface for before/during retries unified
* and logging cut back so only first failure gets logged on a retry loop.
Maybe that could be tuned to remember the previous failure & log if its
different class
* all integration tests excluding rename() ones are now working when tested
with a high (25-50% throttle rate).
* DDB logs of capacity limit failures

HADOOP-13786 MAPREDUCE-6823 FileOutputFormat uses the committer factory,
with tests
commit 1e61b94490fbf3f75330ceea3b5d3b863f5efbe6
Author: Steve Loughran <ste...@apache.org>
Date: 2017-09-19T13:47:44Z
HADOOP-13786
* s/DefaultPutTracker/r/PutTracker. Yes, it is the default one, but its
misleading as a type.
* move to l-expressions in block output stream callables & the committers.
Exception: Tasks.runParallel() whose closure is complex enough that the IDE was
warning about its size. Maybe best to refactor as a method invoked as this::exec
* Adding new statistic, {{committer_bytes_uploaded}}, set when a stream is
closed to #of bytes PUT.
* S3A FS implements {{StreamCapabilities}}, dynamically declares if it is
magic by returning true on {{hasCapability("fs.s3a.magic.enabled")}} when it is.
* S3ABlockOutputStream implements {{StreamCapabilities}}; dynamically
declares if its output has delayed visibility. Also: that it doesn't do
hsync/hflush, obviously.
* {{CommitOperations}}: Experimented with replacing {{MaybeIOE}} with Java
8 Optional<> type. Doesn't work as {{maybeThrow}} can't be implemented as
{{Optional<IOException>.map((e) -> {throw e;})}}; java's checked exceptions
makes maps fairly useless for the Hadoo IOE-throwing APIs. OUutcome:
{{MaybeIOE}} unchanged.
* Minor cleanup of production & test code
* starting to write end user documentation. Needs more clarity on directory
vs partitioned output on staging committer, including examples

HADOOP-13786 HADOOP-14531 rework retry logic, including Ewan's feedback.
New names, les logging. Also, exceptions are translated before the event
handler is called, even if the operation is untranslated. This means the event
handler doesn't need to worry about whether the incoming event is raw/vs
translated

HADOOP-13786 partitioned committer work (+some java 8 bits)

S3AUtils from TestUtils, use in staging committer & commit operations;
* document what partitioned committer does, with notes (needs verification)

HADOOP-13786 MAPREDUCE-6823 remove createCommitter(JobContext) as the only
place a FileOutputCommitter is created off a job context is in the code
bridging from the v1 to v2 APIs of FileOutputFormat. The new factory model
doesn't support v1 MR, so it's not needed. This simplifies testing and allows
for code cutbacks in the s3a implementations & downstream.

commit 8f696e74d0d1d4eb0c3737c21705bc61f06087e8
Author: Steve Loughran <ste...@apache.org>
Date: 2017-10-09T17:19:13Z
HADOOP-13786 S3A committers don't need to support a JobContext in the
constructors or factories: remove, clean up tests. Where tests do need to
create a Committer with nothing but a JobConf, use the same code which MR
itself does for this, now statically exported from AbstractCommitITest

HADOOP-13786: Success marker: Should we delete this when a job starts?
Yes: its presence marks the completion of a job
No: if it contains metadata, that data may be valid until the new data is
present

HADOOP-13786 MAPREDUCE-6823 There's now a "BindingPathOutputCommitter"
which can be instantiated and which relays its invocations to the factory.
This is useful to work with code which takes a committer classname to know what
to instantiated -it allows you to delegate to the factory for dynamic binding
on a per-destination basis.

HADOOP-13786 MAPREDUCE-6823 static method to combine createing factory &
committer in one go; turns out to be a useful operation downstream, so merits
simplification. Tests too.

HADOOP-13786
* WriteOperationHelper no longer takes a key in its constructor, caller
must supply on the relevant ops
* _SUCCESS file includes a name field which is validated on load; goal is
to identify other formats/versions and reject.
* big code review of tests, including renaming, cleanup, IDE-suggested
cleanup
* tests also verify that the hasCapabilities() field returns true for the
magic option on a magic write, false for a non-magic one, even on a magic FS.
