Hi
Try adding solr JAAS config in the conf folder of ranger
> cat ranger_solr_jaas.conf
Client {
com.sun.security.auth.module.Krb5LoginModule required
useKeyTab=true
storeKey=true
useTicketCache=false
keyTab="/opt/mr3-run/ranger/key/rangeradmin.keytab"
principal="rangeradmin/indigo21@RED";
}
Thanks,
Ramesh

Subject: Ranger fails to query to Kerberized Solr
Hi,
I'm trying to dockerize Ranger and Solr in standalone mode for audit store, and
I want Solr to be secure (with Kerberized authentication and authorization).
I tried:
Ranger 1.2.0 + Solr 6.6.6
Ranger 1.2.0 + Solr 8.0.0
Ranger 2.0.0 + Solr 8.0.0 (Ranger 2.0.0 is compiled from the master branch
(8202ed4aed53ad93a21b27dcf83cdf7102678fa0))
I succeeded to open Solr UI with Firefox, and Hive-plugin-enabled HiveServer2
succeeded to log audits to Solr. However, Ranger Admin fails to query to
Kerberized Solr.
Especially, When I login Ranger Admin UI with an admin account, and go to
Audit-Access, the following error message pops up:
Error running solr query, please check solr configs. Error from server at
https://indigo21:6083/solr/ranger_audits: Expected mime type
application/octet-stream but got text/html. <html> <head> <meta
http-equiv="Content-Type" content="text/html;charset=utf-8"/> <title>Error 401
Authentication required</title> </head> <body><h2>HTTP ERROR 401</h2>
<p>Problem accessing /solr/ranger_audits/select. Reason: <pre> Authentication
required</pre></p> </body> </html>
Then, Solr log gives the following error:
(I think Ranger Admin tries to authenticate itself with ID/PW instead of
Kerberos, but why?)

What am I missing? Is there any compatibility issue?
Best regards,
Junseung
P.S. How can I log into Ranger Admin UI with Kerberos ticket? I found out I can
log in with Kerberos ticket in some cases.
