--------------------------------------
Summary: Add the default value for configuration property
ozone.om.kerberos.principal to support cross realm
Key: HDDS-10328
URL: https://issues.apache.org/jira/browse/HDDS-10328
Project: Apache Ozone
Issue Type: Bug
Reporter: Wei-Chiu Chuang
When issuing Ozone commands across clusters in different Kerberos realm, it
produces the following error:
{noformat}
# hdfs dfs -ls ofs://ozone1707264383/
24/02/07 18:47:36 INFO retry.RetryInvocationHandler:

This is because ozone.om.kerberos.principal is not defined properly.
On the contrary, HDFS does not have this issue because HDFS-7546 already added
the default value for dfs.namenode.kerberos.principal.pattern which is wildcard.
We should do the same for ozone.om.kerberos.principal.
