Subject Re: Exceptions in Name node and Data node logs
Date Tue, 13 Aug 2013 09:26:22 GMT
Hi Jitendra,
Thanks for your reply.
Currently my hadoop/hbase is down in production as it had filled up the
disk space with above exceptions in log files  and had to be brought down.
Also i am using hadoop/hbase  in pseudo distributed mode , so there is only
one node which hosts all 6 processes ( 3 from hadoop and 3 from hbase).
