In CatalogJanitor we schedule GCRegionProcedure to clean up both filesystem and in-memory state after a split, and GCMultipleMergedRegionsProcedure to do the same for merges. Both of these procedures clean up in-memory state, but CatalogJanitor also does this redundantly just after scheduling the procedures. The cleanup should be done in only one place. Presumably we are using the procedures to do it in a principled way. Remove the redundancy in CatalogJanitor and fix any follow on issues, like test failures.

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 http://hbase.apache.org/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]. The source code can be found at [5] The HBase issue tracker is at [6] Apache HBase is made available under the Apache License, version 2.0 [7] The HBase mailing lists and archives are listed here [8]. The HBase distribution includes cryptographic software.
