Review request for hbase.
Changes
-------
Updated diff to handle dumb NPE pointed out by tlipcon, also addresses the same
problem in existing code.
Summary
-------
Support alternate compression for major compactions.
This is expected to be an uncommmon configuration so I did not pollute the
HColumnDescriptor constructor with the new option; instead only added
convenience {get,set}ters.
This addresses bug HBASE-2988.

Diffs (updated)
-----
src/main/java/org/apache/hadoop/hbase/HColumnDescriptor.java 8e3bd53

Diff: http://review.cloudera.org/r/821/diff
Testing
-------
Created table with LZO compression, inserted 10GB of data, altered schema with
COMPRESSION_COMPACT of 'LZMA' (custom LZMA Hadoop compression plugin),
initiated major compaction, confirmed the results by examining HFiles on local
fs with the UNIX file utility.
Thanks,
Andrew
