Copy between clusters - multiple fault with using distcp command

Explorer

Hi Community Team, I have performed many tests, here the error:

 

* Both kerberos were configured using this cloudera guide
https://docs.cloudera.com/cdp-private-cloud-base/7.1.5/scaling-namespaces/topics/hdfs-distcp-differe...?

 

Command used:
# hadoop distcp /home/admin/distcp_test.txt hdfs://server8.tm.local:8020/user/admbgdata/

- Different ports have ben used and all fail.
ports= 8020, 8022, (https://docs.cloudera.com/cdp-private-cloud-base/7.1.5/installation/topics/cdpdc-ports-used-by-distc...?)
