Adds override to assigns and unassigns. Changes bypass 'force' to align calling the param 'override' instead. Adds recursive to 'bypass', a means of calling bypass on parent and its subprocedures (usually bypass works on leaf nodes rippling the bypass up to parent -- recursive has us work in the opposite direction): EXPERIMENTAL. bypass on an assign/unassign leaves region in RIT and the RegionStateNode loaded with the bypassed procedure. First implementation had assign/unassign cleanup leftover state. Second implementation, on feedback, keeps the state in place as a fence against other Procedures assuming the region entity, and instead adds an 'override' function that hbck2 can set on assigns/unassigns to override the fencing. Note that the below also converts ProcedureExceptions that come out of the Pv2 system into DoNotRetryIOEs. It is a little awkward because DNRIOE is in client-module, not in procedure module. Previous, we'd just keep retrying the bypass, etc. M hbase-procedure/src/main/java/org/apache/hadoop/hbase/procedure2/Procedure.java Have bypass take an environment like all other methods so subclasses. Fix javadoc issues. M hbase-procedure/src/main/java/org/apache/hadoop/hbase/procedure2/ProcedureExecutor.java Javadoc issues. Pass environment when we invoke bypass. M hbase-server/src/main/java/org/apache/hadoop/hbase/master/HMaster.java Rename waitUntilNamespace... etc. to align with how these method types are named elsehwere .. i.e. waitFor rather than waitUntil.. M hbase-server/src/main/java/org/apache/hadoop/hbase/master/assignment/RegionTransitionProcedure.java Cleanup message we emit when we find an exisitng procedure working against this entity. Add support for a force function which allows Assigns/Unassigns force ownership of the Region entity. A hbase-server/src/test/java/org/apache/hadoop/hbase/master/assignment/TestRegionBypass.java Test bypass and force. M hbase-shell/src/main/ruby/shell/commands/list_procedures.rb Minor cleanup of the json output... do iso8601 timestamps.
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].
