-------------------------------------
Summary: 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.
