This is a first cut at this patch. Implements hold fixing only currently. Add a fixMeta method to Hbck Interface. M hbase-server/src/main/java/org/apache/hadoop/hbase/master/CatalogJanitor.java Bug fix. If hole is on end of last table, I wasn't seeing it. A hbase-server/src/main/java/org/apache/hadoop/hbase/master/MetaFixer.java Add a general meta fixer class. Explains up top why this stuff doesn't belong inside MetaTableAccessor. M hbase-server/src/main/java/org/apache/hadoop/hbase/regionserver/HRegion.java Break out the filesystem messing so don't have to copy it nor do more than is needed doing fixup for Region holes. M hbase-server/src/main/java/org/apache/hadoop/hbase/regionserver/HRegionFileSystem.java Change behavious slightly. If directory exists, don't fail as we did but try and keep going and create .regioninfo file if missing (or overwrite if in place). This should make it idempotent. Can rerun command. Lets see if any repercussions in test suite. A hbase-server/src/test/java/org/apache/hadoop/hbase/master/TestMetaFixer.java Add test.

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.
