Description

From https://builds.apache.org/job/HBase-0.95/455/testReport/org.apache.hadoop.hbase.regionserver/TestStoreFileBlockCacheSummary/testBlockCacheSummary/ :

java.lang.AssertionError: blockCache summary has entries expected:<2> but was:<3>
	at org.junit.Assert.fail(Assert.java:88)
	at org.junit.Assert.failNotEquals(Assert.java:743)
	at org.junit.Assert.assertEquals(Assert.java:118)
	at org.junit.Assert.assertEquals(Assert.java:555)
	at org.apache.hadoop.hbase.regionserver.TestStoreFileBlockCacheSummary.testBlockCacheSummary(TestStoreFileBlockCacheSummary.java:112)

This was due to an additional entry for namespace table:
