Josh Elser bdedcc5631 HBASE-18133 Decrease quota reaction latency by HBase 
Certain operations in HBase are known to directly affect
the utilization of tables on HDFS. When these actions
occur, we can circumvent the normal path and notify the
Master directly. This results in a much faster response to
changes in HDFS usage.

This requires FS scanning by the RS to be decoupled from
the reporting of sizes to the Master. An API inside each
RS is made so that any operation can hook into this call
in the face of other operations (e.g. compaction, flush,
bulk load).

README.txt 

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].
