SolrCloud 4.5.1 and Zookeeper SASL

[Sven Stark <sv...@m-square.com.au>]

Howdy.

We are testing to upgrade Solr from 4.3 to 4.5.1 . We're using SolrCloud
and our problem is that the core does not appear to be loaded anymore.

We've set logging to DEBUG and we've found lots of those

2013-11-12 06:30:43,339 [pool-2-thread-1-SendThread(our.zookeeper.com:2181)]
DEBUG org.apache.zookeeper.client.ZooKeeperSaslClient â<U+0080><U+0093>
Could not retrieve login configuration: java.lang.SecurityException: Unable
to locate a login configuration

Zookeeper is up and running.

Is there any doco on how to disable SASL ? Or what changes were made to
SolrCould exactly?

Much appreciated,
Sven

Shawn,

thanks for taking the time to reply.

Turned out it was something entirely different. We missed to deploy newly
added core.properties file. Adding them immediately fixed everything.
The zookeeper debug messages apparently are there even if SASL is turned
off. We just got sidetracked because there are no error messages related to
the missing file in the logs.

Cheers,
Sven

Something outside Solr probably has turned SASL on.  The Zookeeper
client library in Solr supports SASL, so it is picking up on that and
complaining because it can't find credentials.

It might be a container configuration, so perhaps the config for Tomcat,
Jetty, Glassfish, JBoss, WebSphere, or whatever container you are using
has it turned on.  It might also be something system-wide with Java itself.

If some other software that you are running in your servlet container
requires SASL, then you will either need to move the SASL config to that
specific application, or you will need to put Solr into a separate
container that doesn't have SASL turned on.  The Solr download comes
with a production-quality jetty install (in the example) that's tuned
for a 'typical' small to medium Solr setup.

Thanks,
