URL: https://issues.apache.org/jira/browse/HBASE-12975
Project: HBase
Issue Type: Improvement
Reporter: Rajeshbabu Chintaguntla
Assignee: Rajeshbabu Chintaguntla
Making SplitTransaction, RegionMergeTransaction limited private is required to
support local indexing feature in Phoenix to ensure regions colocation.
We can ensure region split, regions merge in the coprocessors in few method
calls without touching internals like creating zk's, file layout changes or
assignments.
1) stepsBeforePONR, stepsAfterPONR we can ensure split.
2) meta entries can pass through coprocessors to atomically update with the
normal split/merge.
3) rollback on failure.
