Robert Joseph Evans updated STORM-244:
--------------------------------------
Assignee: Kyle Nusbaum
> DRPC timeout can return null instead of throwing an exception
> -------------------------------------------------------------
>
> Key: STORM-244
> URL: https://issues.apache.org/jira/browse/STORM-244
> Project: Apache Storm (Incubating)
> Issue Type: Bug
> Reporter: Robert Joseph Evans
> Assignee: Kyle Nusbaum
> Fix For: 0.9.2-incubating
>
>
> In DPRC there is a race condition when the cleanup method is called between
> releasing the sem, cleaning up the atoms and the blocked thread fetching the
> result. It looks like it is possible on a timeout that the sem will be
> released but by the time the thread blocked on the sem actually wakes up the
> result may have been removed, causing a null to be returned instead of an
> exception being thrown.
