Further investigation after HBASE-15221 lead to some findings that AsyncProcess should have been managing the contents of the region location cache, appropriately clearing it when necessary (e.g. an RPC to a server fails because the server doesn't host that region) For multi() RPCs, the tableName argument is null since there is no single table that the updates are destined to. This inadvertently caused the existing region location cache updates to fail on 1.x branches. AsyncProcess needs to handle when tableName is null and perform the necessary cache evictions. As such, much of the new retry logic in HTableMultiplexer is unnecessary and is removed with this commit. Getters which were added as a part of testing were left since that are mostly harmless and should contain no negative impact. Signed-off-by: stack <stack@apache.org> |

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.
