Subject [jira] [Commented] (ACCUMULO-2291) Update CheckForMetadataProblems to check root table
Date Fri, 21 Feb 2014 20:37:20 GMT

    [ https://issues.apache.org/jira/browse/ACCUMULO-2291?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=13908794#comment-13908794

Keith Turner commented on ACCUMULO-2291:
----------------------------------------

I was looking at the --fix option it makes alot of assumptions, but does not check for these
assumptions.   Looking at the tool I am not convinced that it would not misinterpret a split
as a hole in the metatatable and "fix it" messing up the table.   The tool should probably
check the table is offline and that the tablet has not location before "fixing" a hole.  Also
the deletion of multiple locations seems arbitrary and dangerous, it should probably check
in zookeeper and see what tservers are alive.  If all are alive it probably should not delete
any locations.

> The existing CheckForMetadataProblems only checks the metadata table. It should also
check the root table, now that those are split up.
