-----------------------------------
Summary: MetaTableAccessor.getMergeRegions() returns parent
regions in random order
Key: HBASE-22941
URL: https://issues.apache.org/jira/browse/HBASE-22941
Project: HBase
Issue Type: Bug
Affects Versions: master
Reporter: István Tóth
The multi-region merge patch has changed the behaviour of the
MetaTableAccessor.getMergeRegions() method. Earlier, the parent regions were
returned in the same order that they were passed to mergeRegion().
The patch has changed this to return the regions in random order. To be more
precise, the parent regions are stored in random order in Meta.
I propose storing and returning the parent regions in ascending order.
