Ports
When you use Replication Manager with Kerberos authentication enabled, you need specific ports to be open and accessible.
Make sure that the following ports are open and accessible on the source hosts to allow communication between the source and destination Cloudera Manager servers and the HDFS, Hive, MapReduce, and YARN hosts.
| Service | Default Port |
|---|---|
| Cloudera Manager Admin Console HTTP | 7180 |
| Cloudera Manager Admin Console HTTPS (with TLS enabled) | 7183 |
| Cloudera Manager Agent | 9000 |
| HDFS NameNode | 8020 |
| Key Management Server (KMS) | 16000 |
| HDFS DataNode | 9866 |
| NameNode WebHDFS | 9870 |
| YARN Resource Manager | 8032 |
| DataNode Secure | 1004 |
| NameNode Secure WebHDFS | 9871 |
| Hive Metastore | 9083 |
| Impala Catalog Server | 26000 |
Additionally, the port used for the Kerberos KDC Server and KRB5 services must be open to all hosts on the destination cluster. By default, this is port 88.
