Subject [jira] [Commented] (HBASE-4058) Extend TestHBaseFsck with a complete .META. recovery scenario
Date Sat, 09 Jul 2011 04:28:17 GMT

    [ https://issues.apache.org/jira/browse/HBASE-4058?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=13062317#comment-13062317

stack commented on HBASE-4058:
------------------------------

So I see our fixup tool first running an evaluation on the state of meta and then it would
offer admin choices.  For overlapping regions, we should make it so hbck will run online merge
of the regions that span the broken key area.  If holes, offer to plug the hole.  We should
also offer the option to rebuild from the fs per table or all under hbase.rootdir.

> We should have a unit test that launches a minicluster and constructs a few tables, then
deletes META files on disk, then bounces the master, then recovers the result with HBCK. Perhaps
it is possible to extend TestHBaseFsck to do this.
