dragon created HDFS-10039:
-----------------------------

             Summary: CLONE - StripedBlockUtil.getInternalBlockLength may have overflow error
                 Key: HDFS-10039
                 URL: https://issues.apache.org/jira/browse/HDFS-10039
             Project: Hadoop HDFS
          Issue Type: Sub-task
            Reporter: dragon
            Assignee: Tsz Wo Nicholas Sze
             Fix For: HDFS-7285


Both numStripes and cellSize are int but
{code}
long blkSize = (numStripes - 1) * cellSize;
{code}
When the actually block size > Integer.MAX_VALUE, the computation has overflow error.
