Hi,
I am getting "Check sum ok was sent" errors when I am using hadoop. Can
someone please let me know why this error is coming and how to avoid it.
It was running perfectly fine when I used hadoop-17. And, this error is
coming when I upgraded the system to hadoop-18.2.
The full stack trace is:
08/11/27 13:02:58 INFO fs.FSInputChecker: java.io.IOException: Checksum
ok was sent and should not be sent again
