> Cannot use the namenode for HDFS HA as of Solr 6.4
> --------------------------------------------------
>
> Key: SOLR-10215
> URL: https://issues.apache.org/jira/browse/SOLR-10215
> Project: Solr
> Issue Type: Bug
> Security Level: Public(Default Security Level. Issues are Public)
> Components: Hadoop Integration
> Affects Versions: 6.4.1
> Reporter: Cassandra Targett
>
> As of Solr 6.4, it seems it's no longer possible to use a namenode instead of
> a server address with the {{solr.hdfs.home}} parameter when configuring Solr
> with HDFS high availability (HA).
> Startup is fine, but when trying to create a collection, this error is in the
> logs:
> {code}
> 2017-02-27 22:22:57.359 ERROR (qtp401424608-21) [c:testing s:shard1
> x:testing_shard1_replica1] o.a.s.c.CoreContainer Error creating core
> [testing_shard1_replica1]: Error Instantiating Update Handler,
> solr.DirectUpdateHandler2 failed to instantiate
> org.apache.solr.update.UpdateHandler
> org.apache.solr.common.SolrException: Error Instantiating Update Handler,
> solr.DirectUpdateHandler2 failed to instantiate
> org.apache.solr.update.UpdateHandler
> {code}
> And after the full stack trace (which I will put in a comment), there is this:
> {code}
> Caused by: java.lang.IllegalArgumentException: java.net.UnknownHostException:
> mycluster
> {code}
> I started Solr with the params configured as system params instead of in
> {{solrconfig.xml}}, so my {{solr.in.sh}} has this:
> {code}
> SOLR_OPTS="$SOLR_OPTS $SOLR_ZK_CREDS_AND_ACLS
> -Dsolr.directoryFactory=HdfsDirectoryFactory -Dsolr.lock.type=hdfs
> -Dsolr.hdfs.home=hdfs://mycluster:8020/solr-index
> -Dsolr.hdfs.confdir=/etc/hadoop/conf/"
> {code}
> Solr in this case is running on the same nodes as Hadoop (Hortonworks HDP
> 2.5).
> I tried with a couple variations of defining the Solr home parameter:
> * {{hdfs://mycluster:8020/solr-index}}
> * {{hdfs://mycluster/solr-index}}
> * {{solr-index}}
> None of these variations worked with Solr 6.4.1 (the first 2 got the same
> error as above, the last was just wrong so it got a different error).
> I believe this problem is isolated to Solr 6.4.1. I tested the same setup (as
> in the {{solr.in.sh}} above) with 6.3.0 and it worked fine. Using the server
> address also works fine, but that negates the High Availability feature
> (which is like failover, for those who don't know).
