Subject [jira] [Resolved] (HDFS-8332) DFS client API calls should check filesystem closed
Date Mon, 18 May 2015 09:31:01 GMT

     [ https://issues.apache.org/jira/browse/HDFS-8332?page=com.atlassian.jira.plugin.system.issuetabpanels:all-tabpanel

Uma Maheswara Rao G resolved HDFS-8332.
       Resolution: Fixed
    Fix Version/s:     (was: 2.8.0)
     Release Note: Users may need special attention for this change while upgrading to this
version. Previously user could call some APIs(example: setReplication) even after closing
the fs object. With this change DFS client will not allow any operations to call on closed
fs objects.  As calling fs operations on closed fs is not right thing to do, users need to
correct the usage if any.

> I could see {{listCacheDirectives()}} and {{listCachePools()}} APIs can be called even
after the filesystem close. Instead these calls should do {{checkOpen}} and throws:

> java.io.IOException: Filesystem closed
