---------------------------------------
Summary: CatalogJanitor resubmits GCMultipleMergedRegionsProcedure
for the same region
Key: HBASE-24250
URL: https://issues.apache.org/jira/browse/HBASE-24250
Project: HBase
Issue Type: Bug
Components: master
Affects Versions: 2.2.4
Environment: hdfs 3.1.3 with erasure coding
hbase 2.2.4
Reporter: Andrey Elenskiy
If a lot of regions were merged (due to change of region sizes, for example),
there can be a long backlog of procedures to clean up the merged regions. If
going through this backlog is slower than the CatalogJanitor's scan interval,
it will end resubmitting GCMultipleMergedRegionsProcedure for the same regions
over and over again.
