HConnection#getTable (0.98, 0.99) Replaced HTable under hbase-*/src/main/java. Skipped tests. Would take till end of time to do all and some cases are cryptic. Also skipped some mapreduce where HTable comes through in API. Can do both of these stragglers in another issue. Generally, if a utility class or standalone class, tried to pass in a Connection rather than have the utility or standalone create its own connection on each invocation; e.g. the Quota stuff. Where not possible, noted where invocation comes from... if test or hbck, didn't worry about it. Some classes are just standalone and nothing to be done to avoid a Connection setup per invocation (this is probably how it worked in the new HTable...days anyways). Some classes are not used: AggregationClient, FavoredNodes... we should just purge this stuff. Doc on what short circuit connection does (I can just use it... I thought it was just for short circuit but no, it switches dependent on where you are connecting). Changed HConnection to super Interface ClusterConnection where safe ( internal usage by private classes only). Doc cleanup in example usage so we do new mode rather than the old fashion. Used java7 idiom that allows you avoid writing out finally to call close on implementations of Closeable. Added a RegistryFactory.. moved it out from being inner class. Added a utility createGetClosestRowOrBeforeReverseScan method to Scan to create a Scan that can ... Renamed getShortCircuitConnection as getConnection – users don't need to know what implementation does (that it can short-circuit RPC). The old name gave pause. I was frightened to use it thinking it only for short-circuit reading – that it would not do remote too. Squashed commit of the following: |

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.
