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?)

Here are my settings:

------------- install.properties for Ranger Admin -------------

<configuration>

  <property>

    <name>hadoop.security.authentication</name>

    <value>kerberos</value>

  </property>

</configuration>

What am I missing? Is there any compatibility issue?



Best regards,

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.
