Subject [jira] [Resolved] (ACCUMULO-4332) Tserver exiting due to uncaught error
Date Mon, 19 Mar 2018 18:09:00 GMT


Christopher Tubbs resolved ACCUMULO-4332.
       Resolution: Won't Fix
    Fix Version/s:     (was: 1.7.4)
                       (was: 1.9.0)
                       (was: 2.0.0)

Closing this as "Won't Fix", because the underlying issue appears to have been fixed in newer
versions of Thrift, and in general, it's bad practice to try to catch Errors. Please create
a new issue or pull request at if more work is required
on this.

>          Issue Type: Bug
>    Affects Versions: 1.6.5
>            Reporter: Michael Wall
>            Priority: Major
> After the following log statements, the tserver became a zombie and did nothing but spit
GC and Cache log statements.  The fix was to add more open files, ulimit -n was 1024.  This
ticket is to see if we can catch this exception and kill the tserver.
