> 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.
