Nick Dimiduk created HBASE-23801:
------------------------------------
Summary: ExecutorService ignores Throwables
Key: HBASE-23801
URL: https://issues.apache.org/jira/browse/HBASE-23801
Project: HBase
Issue Type: Bug
Components: regionserver
Affects Versions: 2.3.0
Reporter: Nick Dimiduk
>From the [test
>logs|https://builds.apache.org/job/HBase%20Nightly/job/branch-2/2451/testReport/junit/org.apache.hadoop.hbase.mapred/TestTableMapReduce/health_checks___yetus_jdk8_hadoop2_checks___/]
> of a failed build, I find that the {{ExecutorService}} running in the region
>server appears to ignore exceptions thrown in its executor's tasks. In this
>case, a fatal {{RuntimeException}} was thrown. Instead of aborting the RS, we
>merely log. This results in the region open operation never completing, and
>the test simply hangs.
This implementation is ancient, dating back to HBASE-4281 or before, circa
2011. Thus I assume it impacts all active release lines.
