Simon Minery resolved SOLR-7165.
--------------------------------
Resolution: Fixed
Hadoop High Availability was enabled, completing solr.hdfs.confdir with an
absolute path and completing solr.hdfs.home by the HA link and recreating the
collection did the trick.
> Kerberos authentication always simple
> -------------------------------------
>
> Key: SOLR-7165
> URL: https://issues.apache.org/jira/browse/SOLR-7165
> Project: Solr
> Issue Type: Bug
> Components: Hadoop Integration
> Affects Versions: 5.0
> Environment: CentOS release 6.6
> MIT KDC 5
> Hadoop 2.6.0
> Reporter: Simon Minery
> Labels: hadoop, kerberos
>
> It seems that when creating a collection to HDFS with the " bin/solr create
> -c " command, the authentication is always simple, even with
> <bool name="solr.hdfs.security.kerberos.enabled">true</bool>
> <str name="solr.hdfs.security.kerberos.keytabfile">key.tab</str>
> <str name="solr.hdfs.security.kerberos.principal">principal</str>
> I have two Hadoop clusters, one with simple auth and one kerberized. I can
> correctly add a collection to the first one. I duplicated the solrconfig.xml,
> added the kerberos parameters and I can't add a collection to the second one.
> Here's the bin/solr log:
> bin/solr create -c collectionsecurehdfs -d Solr/collection1/
> Setup new core instance directory:
> Solr/server/solr/collectionsecurehdfs
> Creating new core 'collectionsecurehdfs' using command:
> http://localhost:8983/solr/admin/cores?action=CREATE&name=collectionsecurehdfs&instanceDir=collectionsecurehdfs
> Failed to create core 'collectionsecurehdfs' due to: Error CREATEing SolrCore
> 'collectionsecurehdfs': Unable to create core [collectionsecurehdfs] Caused
> by: hadoop.security.authentication set to: simple, not kerberos, but
> attempting to connect to HDFS via kerberos.
