Bharath Vissapragada c2e01f2398 HBASE-23257: Track clusterID in stand by masters (#798)
This patch implements a simple cache that all the masters
can lookup to serve cluster ID to clients. Active HMaster
is still responsible for creating it but all the masters
will read it from fs to serve clients.

RPCs exposing it will come in a separate patch as a part of
HBASE-18095.

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].
