Description
Saw this in logs:
2008-01-31 18:55:02,128 ERROR org.apache.hadoop.hbase.HRegionServer: Compaction failed for region TestTable,0009438931,1201805282651
java.lang.NullPointerException

Look to see if the response data method needs to be made volatile (There's a test for null just before we use it on line #2262).

This is probably a blocker for 0.16. Changed component to dfs. The fix might be similar to the fix in
HADOOP-2717.
