This patch adds the ability to discover newly added masters dynamically on the master registry side. The trigger for the re-fetch is either periodic (5 mins) or any registry RPC failure. Master server information is cached in masters to avoid repeated ZK lookups. Updates the client side connection metrics to maintain a counter per RPC type so that clients have visibility into counts grouped by RPC method name. I didn't add the method to ZK registry interface since there is a design discussion going on in splittable meta doc. We can add it later if needed.

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.
