Subject [jira] [Commented] (ACCUMULO-1321) Dynamic Classloader lost jars
Date Tue, 30 Apr 2013 02:36:17 GMT

    [ https://issues.apache.org/jira/browse/ACCUMULO-1321?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=13645163#comment-13645163

Hudson commented on ACCUMULO-1321:
----------------------------------

Integrated in Accumulo-1.5 #94 (See [https://builds.apache.org/job/Accumulo-1.5/94/])
    ACCUMULO-1321 - accidently commit a change to reloader time (Revision 1477404)
ACCUMULO-1321 - temporary fix. This will create a new vfs classloader in place, but it leaves
cruft (Revision 1477380)

     Result = UNSTABLE

> 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.
