[jira] [HBASE-4627] Ability to specify a custom start/end to RegionSplitter
Summary:
[HBASE-4627]
added a custom start/end row to RegionSplitter. Also solved
an off-by-one error because the end row is prefix-inclusive and not
exclusive.
<a href="https://issues.apache.org/jira/browse/HBASE-4489"; title="Better key
splitting in RegionSplitter"><del>HBASE-4489</del></a> changed the default
endKey on HexStringSplit from 7FFF... to FFFF... While this is correct,
existing users of 0.90 RegionSplitter have 7FFF as the end key in their schema
and the last region will not split properly under this new code. We need to
let the user specify a custom start/end key range for when situations like this
arise. Optimally, we should also write the start/end key in META so we could
figure this out implicitly instead of requiring the user to explicitly specify
it.
Test Plan:
- mvn test -Dtest=TestRegionSplitter
