Subject [jira] [Created] (HDFS-11719) Arrays.fill() wrong index in BlockSender.readChecksum() exception handling
Date Fri, 28 Apr 2017 18:48:04 GMT
Tao Zhang created HDFS-11719:
--------------------------------

             Summary: Arrays.fill() wrong index in BlockSender.readChecksum() exception handling
                 Key: HDFS-11719
                 URL: https://issues.apache.org/jira/browse/HDFS-11719
             Project: Hadoop HDFS
          Issue Type: Bug
          Components: datanode
            Reporter: Tao Zhang
            Assignee: Tao Zhang


In BlockSender.readChecksum() exception handling part:
Arrays.fill(buf, checksumOffset, checksumLen, (byte) 0);

Actually the paramters should be: Arrays.fill(buf, <startIndex>, <endIndex>, value);
So it should be changed to:
Arrays.fill(buf, checksumOffset, checksumOffset + checksumLen, (byte) 0);
