i'm trying to run a job in <Source_A> Hadoop cluster and it should connect and populate data in <Destination_A> Hadoop Cluster, the problem we are facing recently is, the job running in <Source_A> throwing error like IllegalArgument.Error-Unknown Host: <Destination_B>.
is there any place i should look in and correct coz all the Hosts file entry is perfect only.
please help me to solve this issue.
the Error is:
java.lang.IllegalArgumentException: java.net.UnknownHostException: Destnation_A
