Revision - c847a31 - Print compaction score for every compaction run.

Revision c847a317277c12999bb2fd66a83fb739dcd4c364 authored by Dhruba Borthakur on 04 December 2012, 17:47:05 UTC, committed by Dhruba Borthakur on 04 December 2012, 18:03:47 UTC

Print compaction score for every compaction run.

Summary:
A compaction is picked based on its score. It is useful to
print the compaction score in the LOG because it aids in
debugging. If one looks at the logs, one can find out why
a compaction was preferred over another.

Test Plan: make clean check
