Subject [jira] [Commented] (HDFS-3257) Fix synchronization issues with journal service
Date Thu, 12 Apr 2012 22:47:18 GMT

    [ https://issues.apache.org/jira/browse/HDFS-3257?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=13252943#comment-13252943
] 

Tsz Wo (Nicholas), SZE commented on HDFS-3257:
----------------------------------------------

> ... JournalService RPC server runs using a single thread. ...

I think we are better to assume multiple threads.  Otherwise, read and write from JournalService
cannot be parallel.  Also, the fence response may be slow since it have to wait for other
operations.
