Description

Support request for a major compaction in CompactionTool so that we'll make this nice tool complete and consistent with the other compaction command and API.

After the patch, here is the usage:

Usage: java org.apache.hadoop.hbase.regionserver.CompactionTool \
[-compactOnce] [-major] [-mapred] [-D<property=value>]* files...

Options:
mapred Use MapReduce to run compaction.
compactOnce Execute just one compaction step. (default: while needed)
major Trigger major compaction.
