Subject Re: Datanode Heartbeat Error Messages
Date Wed, 20 Apr 2011 07:53:54 GMT
Hi,
I just did a fresh checkout again and did not find this error,

It turned out this was something a result of my changes locally,
and doing and a fresh checkout did not overwrite it.

Please disregard my previous email, I'm apologized if this alarmed anyone,
I'm still learning the system, so apologies again.

Thanks,
Amit
