# [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.
