Tim Armstrong updated IMPALA-6138:
----------------------------------
Priority: Major (was: Critical)
> Thread creation failure in TAcceptQueueServer may cause crash
> -------------------------------------------------------------
>
> Key: IMPALA-6138
> URL: https://issues.apache.org/jira/browse/IMPALA-6138
> Project: IMPALA
> Issue Type: Bug
> Components: Backend
> Affects Versions: Impala 2.10.0
> Reporter: Sailesh Mukil
> Priority: Major
> Labels: crash
>
> We recently added a patch to catch all exceptions thrown by boost while
> creating threads:
> https://github.com/apache/incubator-impala/commit/e993b9712c81dfb66fdf65bb5269cdc38a8eef18#diff-66eda90b98c0bdfb1cd6e6c0a97e97fa
> However, in one case, we still do not catch the exceptions. We pass in a
> Thread factory into thrift so that it uses Impala code to create threads:
> https://github.com/apache/incubator-impala/blob/master/be/src/rpc/thrift-thread.cc#L57
> And that throws an exception on an inability to create threads:
> https://github.com/apache/incubator-impala/blob/master/be/src/rpc/thrift-thread.cc#L41
> The possible point of failure in TAcceptQueueServer is:
> https://github.com/apache/incubator-impala/blob/master/be/src/rpc/TAcceptQueueServer.cpp#L163
> Nothing catches this exception, which means that if TAcceptQueueServer is
> unable to create a thread, the process will crash.
> One way to handle this would be to have the users of TAcceptQueueServer
> handle exceptions.
