             Summary: Atlas Integration : Atlas fails to come up with solr as indexing search
when the zookeeper quorum has more than one host
                 Key: AMBARI-16464
                 URL: https://issues.apache.org/jira/browse/AMBARI-16464
             Project: Ambari
          Issue Type: Bug
            Reporter: Tom Beerbower
            Assignee: Tom Beerbower


Atlas fails to communicate with solr when the zookeeper quorum has more than one host, as
a result of this atlas fails to comeup.

Actually the config parameter "atlas.graph.index.search.solr.zookeeper-url"  value is set
to "{{zookeeper_quorum}}/logsearch".  Since there are more than one zookeeper servers deployed,
this value evaluates to "[os-r6-apathan-atlas-erie-nosec-3.openstacklocal:2181, os-r6-apathan-atlas-erie-nosec-2.openstacklocal:2181/logsearch]"
which seems to wrong. 

Below is the application log of atlas

The value was set to match the value of the ZK connection string in the logsearch solr-env.sh
 ...

{code}
# Set the ZooKeeper connection string if using an external ZooKeeper ensemble
# e.g. host1:2181,host2:2181/chroot
# Leave empty if not using SolrCloud
ZK_HOST="c6401.ambari.apache.org:2181,c6402.ambari.apache.org:2181,c6403.ambari.apache.org:2181/logsearch"
{code}

It looks like for {{atlas.graph.index.search.solr.zookeeper-url}} it should be ...
{code}
c6401.ambari.apache.org:2181/logsearch,c6402.ambari.apache.org:2181/logsearch,c6403.ambari.apache.org:2181/logsearch
