Steve Loughran updated HADOOP-13171:
------------------------------------
Attachment: HADOOP-13171-branch-2-005.patch
Patch 005: statistics on put and delete operations, more overloaded methods
(exists,() isDirectory()), test on copyFileToLocal to verify that the method
works with the metrics updated in the process.
the ProgressListener class has been factored out and cleaned up for easier
reporting; in the process the various output streams have had a lot of their
use of the s3a client moved into the S3AFilesystem; public methods are provided
which include the instrumentation counter updates.
Also fixes a possible race condition wherein the creation of empty directories
was not being awaited on, which may have been a trigger for some intermittent
race conditions
> Add StorageStatistics to S3A; instrument some more operations
