Subject [jira] [Commented] (ACCUMULO-1937) Thread "tablet assignment 1" died overlaps assigned (tablet) true [] [] []
Date Mon, 02 Dec 2013 14:51:37 GMT

    [ https://issues.apache.org/jira/browse/ACCUMULO-1937?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=13836564#comment-13836564

Keith Turner commented on ACCUMULO-1937:
----------------------------------------

[~ecn] looked at 1.4 this issue exist there ( I did not check 1.5).   Looking at the code
it seems like this issue generates spurious error messages, but does not cause problems (does
not kill the assignment thread because the exception is caught and logged).  Is this what
you saw?

> Running a single node random walk test with two walkers.  I got this error message several
times.
> The way I read this: an assignment was not found in the unopened tablets list.  But unopened,
opening and online tablets are all empty.
> Need to figure out if this condition warrants an error message and squash it if it does
not.
