Summary: Kerberos keytab injection to the agent commands is slow
Key: AMBARI-25468
URL: https://issues.apache.org/jira/browse/AMBARI-25468
Project: Ambari
Issue Type: Bug
Components: ambari-sever
Affects Versions: 2.7.4
Reporter: Dmytro Grinenko
Assignee: Dmytro Grinenko
Fix For: 2.7.6
During test on a big cluster were found that refreshing keytabs operation takes
a long amount of time. The result shows the slowness in injectKeytab operation
caused at the AgentPublishCommands class.
The estimation before looks like 54 mins in total:
~36 mins -> getKerberosDescriptor
~18 mins -> getClusterHostInfo
