   # [DRILL-8275](https://issues.apache.org/jira/browse/DRILL-8275): Prevent the JDBC Client to create error path in Zookeeper
   
   ## Description
   Use the ZK style on the connection string and the zkRoot does not match the actual path of the cluster, then the client always creates the error path (as a permanent) in the Zookeeper.
   
   The reason is that after `CuratorFramework` creates the builder, if `zkRoot` is already specified (called `namespace` in curator), it will force to create the root path (even if the path is inconsistent with the real cluster).
   As the result, many useless roots may be created in Zookeeper.
   
   ## Documentation
   N/A
   
   ## Testing
   Added the tests.
