Anu Engineer commented on HDDS-2175: ------------------------------------ It is something that I disagree with. But if you feel strongly about this; please go ahead. > Propagate System Exceptions from the OzoneManager > ------------------------------------------------- > > Key: HDDS-2175 > URL: https://issues.apache.org/jira/browse/HDDS-2175 > Project: Hadoop Distributed Data Store > Issue Type: Improvement > Components: Ozone Manager > Reporter: Supratim Deka > Assignee: Supratim Deka > Priority: Major > Labels: pull-request-available > Time Spent: 1h > Remaining Estimate: 0h > > Exceptions encountered while processing requests on the OM are categorized as > business exceptions and system exceptions. All of the business exceptions are > captured as OMException and have an associated status code which is returned > to the client. The handling of these is not going to be changed. > Currently system exceptions are returned as INTERNAL ERROR to the client with > a 1 line message string from the exception. The scope of this jira is to > capture system exceptions and propagate the related information(including the > complete stack trace) back to the client. > There are 3 sub-tasks required to achieve this > 1. Separate capture and handling for OMException and the other > exceptions(IOException). For system exceptions, use Hadoop IPC > ServiceException mechanism to send the stack trace to the client. > 2. track and propagate exceptions inside Ratis OzoneManagerStateMachine and > propagate up to the OzoneManager layer (on the leader). Currently, these > exceptions are not being tracked. > 3. Handle and propagate exceptions from Ratis. > Will raise jira for each sub-task. > -- This message was sent by Atlassian Jira (v8.3.4#803005) --------------------------------------------------------------------- To unsubscribe, e-mail: hdfs-issues-unsubscr...@hadoop.apache.org For additional commands, e-mail: hdfs-issues-h...@hadoop.apache.org
