Subject [jira] [Commented] (HDFS-2188) HDFS-1580: Make FSEditLog create its journals from a list of URIs rather than NNStorage
Date Fri, 30 Sep 2011 14:27:45 GMT

    [ https://issues.apache.org/jira/browse/HDFS-2188?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=13118088#comment-13118088
] 

Ivan Kelly commented on HDFS-2188:
----------------------------------

Uploaded new patch, rebased on trunk (over HDFS-2158). I've left in the old constructor now,
it's @VisibleForTesting. 

I didn't changes the FileJournalManager constructor. This would be better done later i think,
once HDFS-2174 is done. We shouldn't move attemptRestoreRemovedStorage into FileJournalManager
at this point, as it would mean that it could get called multiple times if there are multiple
FileJournalManagers.

> Currently, FSEditLog retrieves the list of Journals to create from NNStorage. Obviously
this is file specific. This JIRA aims to remove this restriction to make it possible to create
journals of custom types.
