---------------------------------------
Summary: Do not report errors when the worker shutdown is in
progress
Key: STORM-1600
URL: https://issues.apache.org/jira/browse/STORM-1600
Project: Apache Storm
Issue Type: Improvement
Reporter: Abhishek Agarwal
Assignee: Abhishek Agarwal
Usually in a worker, some uncaught exception in an executor threads leads to
process exit. Process exit is not instantaneous and it first triggers the
shutdown. The shutdown initiation usually results in network connections
closing e.g. zookeeper, hdfs in other threads causing other exceptions. These
threads end up reporting their exceptions as well. It confuses the user who can
these errors on UI but not the actual root cause of shutdown hidden beneath new
errors.
