Subject [jira] [Updated] (HADOOP-13171) Add StorageStatistics to S3A; instrument some more operations
Date Sat, 21 May 2016 18:02:12 GMT

     [ https://issues.apache.org/jira/browse/HADOOP-13171?page=com.atlassian.jira.plugin.system.issuetabpanels:all-tabpanel
]

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
