Subject [jira] [Commented] (HDFS-3695) Genericize format() and initializeSharedEdits() to non-file JournalManagers
Date Wed, 08 Aug 2012 08:21:11 GMT

    [ https://issues.apache.org/jira/browse/HDFS-3695?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=13430939#comment-13430939

Ivan Kelly commented on HDFS-3695:

New patch looks good, though I think FormatConfirmation would be better if called FormatConfirmable.
Why didn't you make JournalManager extend FormatConfirmation? Surely all implementations of
JournalManager will need this functionality.

Since this applies cleanly to trunk, will you be submitting there as well as the QJM branch?

> 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.
