Subject [jira] [Commented] (PHOENIX-3947) Increase scan time out for partial index rebuild and retry only once
Date Wed, 13 Sep 2017 09:24:00 GMT


Ankit Singhal commented on PHOENIX-3947:

[~giacomotaylor], disabling the index by setting disabled timestamp to 0 on any first exception
may result in a need to rebuild all indices during RITs or any instability in HBase cluster,
we should be adding some retries in round robin fashion with some delays before doing this.

> The scan done from MetaDataRegionObserver needs to have a higher timeout so that it can
always complete successfully. The retries should be limited to one too. Upon failure, we should
disable the index and set the INDEX_DISABLE_TIMESTAMP to zero to prevent further attempts
to rebuild the index (as a failure would be an indication that something is awry and manual
intervention should be required to rebuild the index completely).
