Wellington Chevreuil updated HBASE-24877:
-----------------------------------------
Affects Version/s: 3.0.0-alpha-1
> Add option to avoid aborting RS process upon uncaught exceptions happen on
> replication source
> ---------------------------------------------------------------------------------------------
>
> Key: HBASE-24877
> URL: https://issues.apache.org/jira/browse/HBASE-24877
> Project: HBase
> Issue Type: Improvement
> Components: Replication
> Affects Versions: 3.0.0-alpha-1
> Reporter: Wellington Chevreuil
> Assignee: Wellington Chevreuil
> Priority: Major
>
> Currently, we abort entire RS process if any uncaught exceptions happens on
> ReplicationSource initialization. This may be too extreme on certain
> deployments, where custom replication endpoint implementations may choose to
> do so when remote peers are unavailable, but source cluster shouldn't be
> brought down entirely. Similarly, source reader and shipper threads would
> cause RS to abort on any runtime exception occurrence while running.
> This patch adds configuration option (false by default, to keep the original
> behaviour), to avoid aborting entire RS processes under these conditions.
> Instead, if ReplicationSource initialization fails with a RuntimeException,
> it keeps retrying the source startup. In the case of readers/shippers runtime
> errors, it refreshes the replication source, terminating current source and
> its readers/shippers and creating new ones.
