FAQ
Hello everyone,

I am getting this error java.io.IOException: Could not obtain block:,
when running on my new cluster. When I ran the same job on the single
node it worked perfectly, I then added in the second node, and receive
this error. I was running the grep sample job.

I am running Hadoop 0.19.2, because of a dependency on Nutch
(Eventhough this was not a Nutch job). I am not running HBase, the
version of Java is OpenJDK 1.6.0.

Does anybody have any ideas?

Thanks in advance,

-John
