Siddharth Seth commented on HIVE-13187:
---------------------------------------
Another possible place to look at is SQLOperation catching Throwable.
> hiveserver2 can suppress OOM errors in some cases

> Key: HIVE-13187
> URL: https://issues.apache.org/jira/browse/HIVE-13187
> Project: Hive
> Issue Type: Bug
> Affects Versions: 2.0.0
> Reporter: Siddharth Seth
> Priority: Critical
>
> Affects at least branch-2.
> See trace in https://issues.apache.org/jira/browse/HIVE-13176
> This looks to be in src/java/org/apache/hadoop/hive/ql/exec/TaskRunner.java.
> That catches Throwable in the thread and sends it further up. There's no
> checks to see if this is an Error or general Exception - Errors end up
> getting suppressed, instead of killing HiveServer2. This is on the processing
> threads.
> It looks like the Handler threads have some kind of OOM checker on them.
