Subject [jira] [Commented] (ACCUMULO-1321) Dynamic Classloader lost jars
Date Tue, 11 Jun 2013 20:39:20 GMT


Keith Turner commented on ACCUMULO-1321:

bq. Well, this is very similar to that case though.

Its confusing for someone trying to understand what was done when.   Should we change the
description of the ticket to "This ticket covers two similar cases, one of which was fixed
in 1.5.0 and the other which was fixed in 1.5.1 ..."? 

bq. Source code changed, new jar, and instead of copying it in, it's a delete, move, rename.

This sounds like a very nice concise description for a new ticket.

> We have a table setup that uses some custom iterators. We ran an MR job against it without
issues. We then ran the job immediately after the first one wrapped and 2 of my tservers errored
with ClassNotFoundException, even though it ran just fine before.
> Unfortunately we don't have a stack trace (to see if it was breaking differently in the
VFSClassLoader), nor a convenient way to recreate currently. We're working on reproducing
it in order to get more information.
