> --------------------------------------------------------------------------

> Key: PHOENIX-4044
> URL: https://issues.apache.org/jira/browse/PHOENIX-4044
> Project: Phoenix
> Issue Type: Bug
> Affects Versions: 4.10.0
> Reporter: Vikas Vishwakarma
> Priority: Minor
>
> Observing these WARNINGS in the RegionServer logs similar to what is
> discussed PHOENIX-1011
> 2017-07-20 10:10:00,421 WARN [Finalizer] memory.GlobalMemoryManager -
> Orphaned chunk of 15650000 bytes found during finalize
> 2017-07-20 10:10:00,421 WARN [Finalizer] memory.GlobalMemoryManager -
> Orphaned chunk of 15650000 bytes found during finalize
> 2017-07-20 10:10:21,153 WARN [Finalizer] memory.GlobalMemoryManager -
> Orphaned chunk of 15650000 bytes found during finalize
> I am not able to identify the exact sequence of events that lead to these
> warnings but the scenario we were testing is as follows:
> We were trying to simulate Index update failures for one of our tests to
> check index rebuild scenario
> For this we did a close_region on one of the index table regions so that all
> updates on this region will fail with NSRE
> With this we start seeing index update failures, scanner lease expiries, etc
> After sometime we re-assign the closed_region to trigger index rebuild
> We start seeing these WARNING messages related to Orphaned chunks in
> Regionserver logs in this case
