     [ https://issues.apache.org/jira/browse/HADOOP-6432?page=com.atlassian.jira.plugin.system.issuetabpanels:all-tabpanel
]

Jitendra Nath Pandey updated HADOOP-6432:
-----------------------------------------

    Attachment: HADOOP-6432.3.patch

A few points regarding the patch: 
  1. The Statistics are statically stored inside AbstractFileSystem in a map that is keyed
on URI. Only scheme and authority part of the URI are used. 
  2. API are added to FileContext to get the statistics. 
  3. FileContext.getAllStatistics returns a map of URI and statistics, but the URI key contains
only scheme and authority.
