* sometimes API calls return with null/empty response bodies. thus, wrap all API calls in a retry loop. * calls that submit work in the form of "commands" now retrieve the commandId from successful command submission, and track completion of that command before returning control to calling context. * model CM's process state and use that model to guide state transitions more intelligently. this guards against, for example, the start command failing with an error message like "Role must be stopped". * improvements to logging levels, avoid spamming logs with the side-effects of retries at this and higher contexts. * include references to API documentation, such as it is.

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. See the export control notice here [9]. 1. http://hbase.apache.org 2. http://research.google.com/archive/bigtable.html 3. http://hadoop.apache.org 4. http://www.apache.org/dyn/closer.cgi/hbase/ 5. https://hbase.apache.org/source-repository.html 6. https://hbase.apache.org/issue-tracking.html 7. http://hbase.apache.org/license.html 8. http://hbase.apache.org/mail-lists.html 9. https://hbase.apache.org/export_control.html
