---------------------------------------------------
Key: HADOOP-2674
URL: https://issues.apache.org/jira/browse/HADOOP-2674
Project: Hadoop
Issue Type: Bug
Components: contrib/hbase
Environment: hadoop svn 613782
Reporter: Billy Pearson
Priority: Minor
Fix For: 0.16.0
below shows a memcache size of 64M but when you add up the regions I get
149.3K = 152883.2B
153B = 153B
153B = 153B
3.8M = 3984588.8B
2.6M = 2726297.6B
153B = 153B
129K = 132096B
2.6M = 2726297.6B
153B = 153B
total = 9569891.4B = 9.12M not 64M
