Fix two issues: # Meta Replicas can all be assigned to the same server. This will call the test to hang when we do our kill of the server hosting meta because there'll be no replicas to read from as test intends. Check is to look for this condition on startup and adjust if we come across it. Replicas cross-cut assignment. They need work. # Other issue was shutdown. The master started toward the end of the test may not have come up fully by the time shutdown is called. We could be stuck assigning the meta replicas. Have shutdown shutdown the procedure executor engine. There is other cleanup and notes in the below. M HMaster Remove the silly stops in startup now we have real means of shutting down Master during init. M hbase-server/src/main/java/org/apache/hadoop/hbase/master/MasterMetaBootstrap.java This replica stuff was doing stuff it shouldn't be doing like setting core Master state flags. It may have made sense once but now meta is assigned by a Pv2 Procedure so the flag setting in here is meddlesome. Clear out methods no longer needed. M hbase-server/src/main/java/org/apache/hadoop/hbase/master/assignment/AssignmentManager.java Remove unused methods. Changes local variable names so they align w/ our naming elsewhere in code base. M hbase-server/src/test/java/org/apache/hadoop/hbase/client/TestMetaWithReplicas.java Check for all replicas on the one server.
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].
