[jira] [Commented] (HIVE-3008) Memory leak in TUGIContainingTransport

    [ https://issues.apache.org/jira/browse/HIVE-3008?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=13270134#comment-13270134 ] 

Ashutosh Chauhan commented on HIVE-3008:
----------------------------------------

There is a weakhashmap which is from TTransport->TUGIContainingTransport. The map is weak so that when TTransport gets out of scope, it can be GC'ed even though map contains a reference to it. But, since TUGIContainingTransport contains a reference to TTransport, even when TTransport is out of scope otherwise, its ref is still retained. Solution is to wrap reference of TTransport in TUGIContainingTransport in WeakReference.
