: Everything is working OK, I just receive this warning message so often:
:
: 2021-09-01 20:29:46.789 WARN (qtp1533985074-61) [ ]
o.a.h.s.a.u.KerberosName auth_to_local rule mechanism not set.Using default of
hadoop
...
: file. As I understand this warning should be if I use HDFS or Hadoop
: Authentication but this is not the case.
IIUC, the Solr KerberosPlugin uses hadoop Kerberos utility classes
under the covers, even when you aren't explicitly using hadoop based
authentication ... i gather that one/some of those utilities make
assumptions about how they are being used.
I don't know that there is anything you personally can change about how
solr is configured to prevent this WARN from happening ... from poking
around the KerberosName.java code, i gather that somewhere in the Solr
KerberosPlugin lifecycle, solr should be calling
KerberosName.setRuleMechanism(...) (or calling some other hadoop kerberos
helper util in such a way that it calls that method)
Can you please file a jira pointing out this warning and this email
thread? ... in the meantime i think the only thing you can do is disable
the WARN level from the KerberosName logger in your log4j config.
