Andrew Purtell e4d2895cad HBASE-27166 WAL value compression minor improvements (#4584) 
A larger IO buffer for absorbing WALCodec writes can improve the compression
ratio of larger values, because the compressor will be given a larger internal
buffer over which there will be more match opportunities. Does not impact the
ability to read existing written files.

Also, reset the BAOS internal buffer on the way out of compress() so potential
large-ish buffers do not linger on the heap longer than necessary.

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]
