Hello, I wrote to the mailing list because I don't know how to get rid of that warning properly. A person who replied me in the mailing list asked me to open a Jira issue for this: 

[https://www.mail-archive.com/users@solr.apache.org/msg01463.html]

I configured Solr authentication this guide:

[https://solr.apache.org/guide/8_9/kerberos-authentication-plugin.html]

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

I don't know what to do to get rid of this. I personally want to make a right configuration in the right fil*e instead of just disabling the warning*.

I just configured the "[solr.kerberos.name|http://solr.kerberos.name/] <[http://solr.kerberos.name>.rules]" in the [solr.in.sh|http://solr.in.sh/] <[http://solr.in.sh>]; but it seems to be ignored.  I don't know if I have to make an extra configuration in the FreeIPA or maybe I am missing another configuration file. As I understand this warning should be if I use HDFS or Hadoop Authentication but this is not the case.

This is the content of my "solr.in.sh"  file:

SOLR_AUTH_TYPE="kerberos"

At the moment I just modified the file log4j2.xml with this content:

 
{code:java}
<AsyncLogger name="org.apache.hadoop.security.authentication.util.KerberosName" level="off"/>{code}
 

I could disable the warning but as I said I would like to know another way different to this.

 

Best regards.
