Subject [jira] [Commented] (HDFS-2334) Add Closeable to JournalManager
Date Fri, 21 Oct 2011 23:48:32 GMT

    [ https://issues.apache.org/jira/browse/HDFS-2334?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=13133196#comment-13133196

Jitendra Nath Pandey commented on HDFS-2334:

In JournalAndStream#close, stream may already be closed and may be null. You probably need
to check for null for stream.

> A JournalManager may take hold of resources for the duration of their lifetime. This
isn't the case at the moment for FileJournalManager, but BookKeeperJournalManager will, and
it's conceivable that FileJournalManager could take a lock on a directory etc. 
> This JIRA is to add Closeable to JournalManager so that these resources can be cleaned
up when FSEditLog is closed.
