Unknown Host exception

[FATAL]: entops_ops.job_opsbi_generic_ingestion_0_1.Job_opsbi_generic_ingestion - tSqoopImport_1 java.net.UnknownHostException: TDHFD4
java.lang.IllegalArgumentException: java.net.UnknownHostException: TDHFD4

 

 

Getting Unknown Host exception while trying to do sqoop import, I have used built in connection.

Is there something to do with sqoop-site.xml configuration, that file in cluster is empty.

Hello,

Did you configure IP address or Hostname all the way in your cluster?

There must be something wrong with internal communication of the nodes within the cluster.you can start adding all the host entries in hosts file.
Hadoop is normally biased towards hostnames because
1) it allows HA systems with floating IP addresses to move the host around
2) Kerberos wants hostnames, not IP Address
3) DNS and rDNS working is effectively a requirement for a functional Hadoop cluster.

Let us know if it helps.

Best regards

Sabrina
