Review request for accumulo.
Changes
-------
Link to the JIRA issue.
Bugs: ACCUMULO-2632
https://issues.apache.org/jira/browse/ACCUMULO-2632
Repository: accumulo
Description
-------
The goal was to find a way to increase the write speed in the DfsLogger using
compression.
This patch uses the Snappy compression library and was the most optimum way
that I could find to increase write performance.
The option to use compression has been made configurable.
Recovery has been modified to uncompress the WAL if needed.
