[jira] [Commented] (ACCUMULO-1321) Dynamic Classloader lost jars

    [ https://issues.apache.org/jira/browse/ACCUMULO-1321?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=13635920#comment-13635920 ] 

Dave Marion commented on ACCUMULO-1321:
---------------------------------------

Any update? Also, can you give details as to the configuration of the system? There should also be some output from the vfs related code in the tserver debug logs.

> 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.
