HADOOP-16665. Filesystems to be closed if they failed during initialize().

Contributed by Steve Loughran.

This FileSystem instantiation so if an IOException or RuntimeException is

raised in the invocation of FileSystem.initialize() then a best-effort

attempt is made to close the FS instance; exceptions raised that there

are swallowed.

The S3AFileSystem is also modified to do its own cleanup if an

IOException is raised during its initialize() process, it being the

FS we know has the "potential" to leak threads, especially in

extension points (e.g AWS Authenticators) which spawn threads.

Revert "HADOOP-15870. S3AInputStream.remainingInFile should use nextReadPos."

This reverts commit 7a4b3d42c4e36e468c2a46fd48036a6fed547853.

The patch broke TestRouterWebHDFSContractSeek as it turns out that

WebHDFSInputStream.available() is always 0.

HADOOP-16570. S3A committers encounter scale issues.

Contributed by Steve Loughran.

This addresses two scale issues which has surfaced in large scale benchmarks

of the S3A Committers.

* Thread pools are not cleaned up.

This now happens, with tests.

* OOM on job commit for jobs with many thousands of tasks,

each generating tens of (very large) files.

Instead of loading all pending commits into memory as a single list, the list

of files to load is the sole list which is passed around; .pendingset files are

loaded and processed in isolation -and reloaded if necessary for any

abort/rollback operation.

The parallel commit/abort/revert operations now work at the .pendingset level,

rather than that of individual pending commit files. The existing parallelized

Tasks API is still used to commit those files, but with a null thread pool, so

as to serialize the operations.

HADOOP-16207 Improved S3A MR tests.

Contributed by Steve Loughran.

Replaces the committer-specific terasort and MR test jobs with parameterization

of the (now single tests) and use of file:// over hdfs:// as the cluster FS.

The parameterization ensures that only one of the specific committer tests

run at a time -overloads of the test machines are less likely, and so the

suites can be pulled back into the parallel phase.

There's also more detailed validation of the stage outputs of the terasorting;

if one test fails the rest are all skipped. This and the fact that job

output is stored under target/yarn-${timestamp} means failures should

be more debuggable.

HADOOP-16458. LocatedFileStatusFetcher.getFileStatuses failing intermittently with S3

Contributed by Steve Loughran.


-S3A glob scans don't bother trying to resolve symlinks

-stack traces don't get lost in getFileStatuses() when exceptions are wrapped

-debug level logging of what is up in Globber

-Contains HADOOP-13373. Add S3A implementation of FSMainOperationsBaseTest.

-ITestRestrictedReadAccess tests incomplete read access to files.

This adds a builder API for constructing globbers which other stores can use

so that they too can skip symlink resolution when not needed.

HADOOP-15691 Add PathCapabilities to FileSystem and FileContext.

Contributed by Steve Loughran.

This complements the StreamCapabilities Interface by allowing applications to probe for a specific path on a specific instance of a FileSystem client

to offer a specific capability.

This is intended to allow applications to determine

* Whether a method is implemented before calling it and dealing with UnsupportedOperationException.

* Whether a specific feature is believed to be available in the remote store.

As well as a common set of capabilities defined in CommonPathCapabilities,

file systems are free to add their own capabilities, prefixed with

fs. + schema + .

The plan is to identify and document more capabilities -and for file systems which add new features, for a declaration of the availability of the feature to always be available.


* The remote store is not expected to be checked for the feature;

It is more a check of client API and the client's configuration/knowledge

of the state of the remote system.

* Permissions are not checked.

HADOOP-16371: Option to disable GCM for SSL connections when running on Java 8.

Contributed by Sahil Takiar.

This moves the SSLSocketFactoryEx class from hadoop-azure into hadoop-common

as the DelegatingSSLSocketFactory and binds the S3A connector to it so that

it can avoid using those HTTPS algorithms which are underperformant on Java 8.
