URL: https://github.com/apache/hadoop/pull/1637
https://issues.apache.org/jira/browse/HDDS-2206
Introduced a boolean config parameter to control exception propagation from OM to Clients.
If set to true, all system exceptions (IOException) are thrown as ServiceException to RPC client - this also propagates the complete server-side stack trace to the client. If false, system exception stack trace is logged locally on the server, not sent to client.
The default value is set to true for now. For Ozone GA, we can revisit this choice.
Business Exception (OMException) handling is not changed.
This change does not include propagation of exceptions from within Ratis server.
