URL: https://github.com/apache/hbase/pull/8264
- Bug: When a host RegionServer and master crashes, regionCrashed() blindly
added all hosted regions to RIT, including split-completed parent regions that
should never be reassigned.
- Fix: Added isSplitOrMerged() guard in regionCrashed() to skip
split/merged regions. Extracted isSplitOrMerged() and isReplica() helpers to
reduce duplication with handleRegionStateNodeOperation().
- Removed broken isRegionInTransition(RegionInfo) API —
RegionInfo.COMPARATOR considers offline/split flags, so lookups failed when
those flags differed between the query and stored instance. Replaced
with encoded-name-based lookup in test utility.
- Added test testRITWithSplitTableRegion — splits a region, crashes the
hosting RS, restarts the master, and verifies the split parent is NOT in the
RIT list.
