Hairong Kuang commented on HADOOP-4506:
---------------------------------------
The error message was introduced by HADOOP-3914 in 0.19 mainly for the
debugging purpose. So Suman, please no panic! Every of your jobs should still
be successfully finished. Raghu has already found out the cause of multiple
checksum Ok messages. He is going to fix the problem and remove the logging in
HADOOP-4499. I will close this jira and mark it as a duplicate of HADOOP-4499.
Thanks Surman and please follow jira 4499.
