Phabricator commented on HBASE-4627: ------------------------------------ Karthik has commented on the revision "[jira] [HBASE-4627] Ability to specify a custom start/end to RegionSplitter". INLINE COMMENTS src/main/java/org/apache/hadoop/hbase/util/Bytes.java:1371 Formatting nit: if() return null; src/main/java/org/apache/hadoop/hbase/util/Bytes.java:1417 Trying to reason with this one - so to make it an inclusive range, we are making the delta [ (end - start)/numSplits + 1 ]. Wondering if that would always give the required number of uniform sized regions. REVISION DETAIL https://reviews.facebook.net/D39 COMMITS https://reviews.facebook.net/rHBASE1196256 https://reviews.facebook.net/rHBASE1196772 > Ability to specify a custom start/end to RegionSplitter > ------------------------------------------------------- > > Key: HBASE-4627 > URL: https://issues.apache.org/jira/browse/HBASE-4627 > Project: HBase > Issue Type: Improvement > Affects Versions: 0.94.0 > Reporter: Nicolas Spiegelberg > Assignee: Nicolas Spiegelberg > Attachments: D39.1.patch, D39.1.patch > > > HBASE-4489 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. -- This message is automatically generated by JIRA.
