-------------------------------------
Summary: Make KillServerOnFailurePolicy a configurable option in
PhoenixIndexFailurePolicy
Key: PHOENIX-4977
URL: https://issues.apache.org/jira/browse/PHOENIX-4977
Project: Phoenix
Issue Type: Bug
Affects Versions: 4.14.0
Reporter: Vincent Poon
Currently PhoenixIndexFailurePolicy, which is the default policy, delegates to
KillServerOnFailurePolicy. This is hardcoded in the constructor. Apparently
this was added for a specific use case,
BLOCK_DATA_TABLE_WRITES_ON_WRITE_FAILURE, and the policy itself derives from
the days where forcing a RS kill was in effect the way to 'rebuild' the index
via WAL replay.
There are still cases where it's applicable, such as when Syscat itself cannot
be updated in order to e.g. disable an index. However, killing the RS may be
too aggressive for some, who might prefer a temporarily out of sync index to a
potentially cascading wave of aborts.
We should add a config option to control this.
