RegionSplitter : Utility class for manual region splitting
----------------------------------------------------------
Key: HBASE-3448
URL: https://issues.apache.org/jira/browse/HBASE-3448
Project: HBase
Issue Type: New Feature
Components: client, scripts, util
Reporter: Nicolas Spiegelberg
Assignee: Nicolas Spiegelberg
Priority: Minor
Fix For: 0.90.1
For certain use cases, there are a number of advantages to manually splitting
regions instead of having the HBase split code determine this for you
automatically. There are currently some API additions to HBaseAdmin and HTable
that allow you to manually split on a small scale. This JIRA is about
importing a RegionSplitter utility program to help pre-split and perform
rolling splits on a live table when needed. Will also add documentation to
answer common questions about why you would pre-split.
