Viraj Jasani commented on PHOENIX-7346:
---------------------------------------
Yes, this is a known issue. We have done some improvements with PHOENIX-7076
that you might be interested in.
If you are no longer using old indexing framework, please feel free to keep
value of config "phoenix.index.failure.handling.rebuild" as "false" and you
would likely never face this issue. Also, if you are not using stats feature,
the config value for "phoenix.stats.collection.enabled" would also be "false",
it is an additional improvement to make MetaDataRegionObserver coproc a no-op.
