Could you post the relevant parts of the logs where the error shows?
I am running MapReduce job over HBase-0.94.3 and Hadoop-1.0.3 cluster of 3 machines but it gives me error as Null pointer exception. Caused by ReverseDNS.
When I tried to run MapReduce job over Hadoop it gets executed perfectly.
How to resolve it?
Thanks in advance.
