----------------------------------

             Summary: Unify blocksize after encoding to decrease memory fragment 
                 Key: HBASE-17757
                 URL: https://issues.apache.org/jira/browse/HBASE-17757
             Project: HBase
          Issue Type: New Feature
            Reporter: Allan Yang
            Assignee: Allan Yang


Usually, we store encoded block(uncompressed) in blockcache/bucketCache. Though we have set
the blocksize, after encoding, blocksize is varied. Varied blocksize will cause memory fragment
problem, which will result in more FGC finally.In order to relief the memory fragment, This
issue adjusts the encoded block to a unified size.
