[jira] [Comment Edited] (HBASE-21464) Splitting blocked with meta
NSRE during split transaction
[ https://issues.apache.org/jira/browse/HBASE-21464?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=16687667#comment-16687667 ]

--------------------------------------------------------------
IIRC, RegionLocations is for region replica, as in its comments "Container for holding a list of {HRegionLocation's that correspond to the same range". Merge all regions in one table(different ranges) to one RegionLocations may not semantically right, IMHO.
