Subject [jira] [Commented] (HDFS-2092) Remove configuration object reference in DFSClient
Date Thu, 23 Jun 2011 22:56:47 GMT

    [ https://issues.apache.org/jira/browse/HDFS-2092?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=13054159#comment-13054159
] 

Eli Collins commented on HDFS-2092:
-----------------------------------

Does this change mean that a Configuration object can now bee free'd because there's one fewer
ref to it?  Otherwise it seems like we're now allocating a DFSClient#conf in addition to a
Configuration object which increases over all memory usage no?

> At present, DFSClient stores reference to configuration object. Since, these configuration
objects are pretty big at times can blot the processes which has multiple DFSClient objects
like in TaskTracker. This is an attempt to remove the reference of conf object in DFSClient.
