> 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
