Steve Loughran updated HADOOP-13171:
------------------------------------
Attachment: HADOOP-13171-branch-2-004.patch
Patch 004.
Synced with branch-2
Add counters for the FS API invocations, subclassing some more of the
FileSystem methods so they can be counted. The bulk list/glob calls are very
expensive; counting their use identifies calling code which could be improved.
With the precursor code in, this is ready for review
> Add StorageStatistics to S3A; instrument some more operations
