Subject Exceptions in Name node and Data node logs
Date Tue, 13 Aug 2013 08:23:37 GMT
Hi,
I have configured Hadoop and Hbase in pseudo distributed mode.
So far things were working fine , but suddenly i started receiving some
exceptions in my namenode and datanode log files.
It keeps repeating and thus fills up my disk space.
Please help here.

*Exception in data node :-*
