Summary: Orphaned chunk of 15650000 bytes found during finalize
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
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
