Subject [jira] [Created] (HDFS-3695) Genericize format() and initializeSharedEdits() to non-file JournalManagers
Date Fri, 20 Jul 2012 01:11:36 GMT
Todd Lipcon created HDFS-3695:
---------------------------------

             Summary: Genericize format() and initializeSharedEdits() to non-file JournalManagers
                 Key: HDFS-3695
                 URL: https://issues.apache.org/jira/browse/HDFS-3695
             Project: Hadoop HDFS
          Issue Type: Sub-task
          Components: ha, name-node
    Affects Versions: QuorumJournalManager (HDFS-3077)
            Reporter: Todd Lipcon
            Assignee: Todd Lipcon


Currently, the "namenode -format" and "namenode -initializeSharedEdits" commands do not understand
how to do anything with non-file-based shared storage. This affects both BookKeeperJournalManager
and QuorumJournalManager.

This JIRA is to plumb through the formatting of edits directories using pluggable journal
manager implementations so that no separate step needs to be taken to format them -- the same
commands will work for NFS-based storage or one of the alternate implementations.
