-----------------------------
Summary: Add a multi-region merge (for fixing overlaps)
Key: HBASE-22777
URL: https://issues.apache.org/jira/browse/HBASE-22777
Project: HBase
Issue Type: Sub-task
Components: hbck2, proc-v2
Reporter: stack
MergeTableRegionProcedure does two regions at a time only. We have hardcoded
notion that merge has an 'A' and 'B' parent.
This issue is about making it so we merge N regions all in the one go. We need
this facility generally; will simplify operator's life being able to merge up
in one go rather than in steps of two. In particular, would make fixing
overlaps easier if could just merge all regions in the overlapping area.
