      Description

      On a test system got this exception when hfile.block.cache.size is set to 0:

      java.lang.NullPointerException
      at org.apache.hadoop.hbase.io.hfile.HFileReaderV2.close(HFileReaderV2.java:321)

      Minor issue as nobody in their right mind with have hfile.block.cache.size=0

      Looks like this is due to HBASE-4422
