Hi all,
I'm trying to install Hadoop on a cluster, but I'm getting this error.
I'm using java version "1.6.0_17" and hadoop-0.20.1+169.56.tar.gz from
Cloudera.
Its running in a NFS home shared between the nodes and masters.
The NameNode works well, but all nodes try to connect and fail.
Any Idea ?
Thanks in Advance.
