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.

Apache HBase [1] is an open-source, distributed, versioned, column-oriented store modeled after Google' Bigtable: A Distributed Storage System for Structured Data by Chang et al.[2] Just as Bigtable leverages the distributed data storage provided by the Google File System, HBase provides Bigtable-like capabilities on top of Apache Hadoop [3]. To get started using HBase, the full documentation for this release can be found under the doc/ directory that accompanies this README. Using a browser, open the docs/index.html to view the project home page (or browse to [1]). The hbase 'book' at docs/book.html has a 'quick start' section and is where you should being your exploration of the hbase project. The latest HBase can be downloaded from an Apache Mirror [4].
