------------------------------------------------
Summary: Make sure local indexes work properly after fixing region
overlaps by HBCK.
Key: PHOENIX-2737
URL: https://issues.apache.org/jira/browse/PHOENIX-2737
Project: Phoenix
Issue Type: Bug
Reporter: Rajeshbabu Chintaguntla
Assignee: Rajeshbabu Chintaguntla
Fix For: 4.8.0
When there are region overlaps hbck fix by moving hfiles of overlap regions to
new region of common key of overlap regions. Then we might not properly replace
region start key in HFiles in that case. In this case we don't have any
relation of parent child region in hbase:meta so we cannot identify the start
key in HFiles. To fix this we need to add separator after region start key so
that we can easily identify start key in HFile without always touching
hbase:meta. So when we create scanners for the Storefiles we can check the
region start key in hfile with region start key and if any change we can just
replace the old start key with current region start key. During compaction we
can properly replace the start key with actual key values.
