Subject [jira] Commented: (HADOOP-4499) DFSClient should invoke checksumOk only once.

Hairong Kuang commented on HADOOP-4499:
---------------------------------------

OK I see. Now I understand the code better. The problem was caused by the data buffering.
The confusing part is that gotEOS represents the end of "raw" stream not the block stream.

+1.

> This is a follow up for HADOOP-3914. HADOOP-3914 added a log when DFSClient tries to
invoke checksumOk more than once. This jira is mainly for removing the debug log since we
know why it happens.
