New tool to dump existing replication peers, configurations and
queues when using HBase Replication. The tool provides two flags:
--distributed This flag will poll each RS for information about
the replication queues being processed on this RS.
By default this is not enabled and the information
about the replication queues and configuration will
be obtained from ZooKeeper.
--hdfs When --distributed is used, this flag will attempt
to calculate the total size of the WAL files used
by the replication queues. Since its possible that
multiple peers can be configured this value can be
overestimated.

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.
