    Hi All,
    Am trying to install Hortonworks Hadoop single node cluster, am able to start namenode,secondary namenode but datanode failed with the below error. Can you please advice me on how to solve this issue.

    “2014-04-04 18:22:49,975 FATAL datanode.DataNode (DataNode.java:secureMain(1841)) – Exception in secureMain java.lang.RuntimeException: Although a UNIX domain socket path is configured as /var/lib/hadoop-hdfs/dn_socket, we cannot start a localDataXceiverServer because libhadoop cannot be loaded.”

    Hi Selvam,

    Did you manually install the cluster or did you use Ambari?

    It looks like you have not set the environment variables correctly.

    Thanks

    Dave
