This appears to result from here
[SolrDao.java#L137-L144|https://github.com/apache/metron/blob/feature/METRON-1416-upgrade-solr/metron-platform/metron-solr/src/main/java/org/apache/metron/solr/dao/SolrDao.java#L137-L144]
In `getSolrClient`, `withZkHost` should be called multiple times after
splitting the comma delimited string, per
[CloudSolrClient.Builder#withZkHost|https://lucene.apache.org/solr/6_5_0/solr-solrj/org/apache/solr/client/solrj/impl/CloudSolrClient.Builder.html#withZkHost-java.lang.String-].
Overall, this could probably be done a couple ways, either to just split the
String directly, or rearrange the methods to pass around Lists and have
`getZkHost` be changed to `getZkHosts` and take care of it in a more contained
manner.
