Andrew Purtell a1d59bf1a5 HBASE-25994 Active WAL tailing fails when WAL value compression is enabled (#3377)
Depending on which compression codec is used, a short read of the
compressed bytes can cause catastrophic errors that confuse the WAL reader.
This problem can manifest when the reader is actively tailing the WAL for
replication. To avoid these issues when WAL value compression is enabled,
BoundedDelegatingInputStream should assume enough bytes are available to
supply a reader up to its bound. This behavior is valid per the contract
of available(), which provides an _estimate_ of available bytes, and
equivalent to IOUtils.readFully but without requiring an intermediate
buffer.

Added TestReplicationCompressedWAL and TestReplicationValueCompressedWAL.
Without the WALCellCodec change TestReplicationValueCompressedWAL will
fail.

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].
