No route to host exception while running sqoop commands


#1

Hello,
I am getting the below exception while running sqoop commands
18/04/23 14:00:17 INFO hdfs.DFSClient: Exception in createBlockOutputStream
java.net.NoRouteToHostException: No route to host

Can you please help me on this issue
I am not sure whether the problem is with my system or from the cluster

Looks like there is issue with cluster itself . Even I’m getting the same error for just copying files to local unix machine.

Lets wait for some more time
