> Zookeeper parameter in Phoenix JDBC URL should be optional as it can be

> Project: Phoenix
> Issue Type: Task
> Affects Versions: 1.1
> Reporter: mujtaba
> Labels: enhancement
>
> Currently, value from HBase zookeeper/port specified in Phoenix JDBC URL
> overrides the value specified in hbase-site.xml. Override is fine, but it
> should use value specified in hbase-site.xml if no value is specified in
> phoenix JDBC URL i.e. to make this parameter optional.
