README

        
Source code for the internal HBase offline compacter.  This runs

during off-peak hours and cycles through all the region servers and

kicks off region compactions, one region at a time.  It then pauses

for a few seconds (configurable) and repeats the process till all the

regions are done.  The program also queries the current compaction

queue on the servers (via jmx) and skips the server if the queue size

is too high (configurable).  Also, it only runs during off-peak hours

(configurable as well).

The program expects JMX credentials in a text file with the format

role password

The name of this text file is hard coded in the JMXQuery.java file.

You will probably need the following libraries to get this to run.
