> Key: HDFS-11719
> URL: https://issues.apache.org/jira/browse/HDFS-11719
> Project: Hadoop HDFS
> Issue Type: Bug
> Components: datanode

>
> 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);
