Review request for Ambari, John Speidel and Nate Cole.


Bugs: AMBARI-16464
    https://issues.apache.org/jira/browse/AMBARI-16464


Repository: ambari


Description
-------

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

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]".

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

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