hi community cloudera, i have a cluster with two Zookeepers. 1. Zookeeper is used by all services in the cluster. 2. Zookeeper-kfk is used by the Kafka service. however, for Ranger to manage permissions in Kafka, Kafka needs to use the same Zookeeper that Ranger uses. therefore, I need to merge the two Zookeepers. I've tried using zkcopy.py, but I always get the error "ERROR: Source path "/var/lib/zookeeper" does not exist.", but the directory exists in the source. ls -l /var/lib/zookeeper total 8 -rw-r--r-- 1 zookeeper zookeeper 2 Oct 8 11:24 myid drwxr-xr-x 2 zookeeper zookeeper 4096 Oct 8 11:25 version-2 cloudera's official support doesn't have a procedure for this issue. Therefore, I'd like to know if anyone has managed to run zkcopy.py with success or used another method to merge two Zookeepers in the same cluster?

hi @Zainers , you must specify the class name according to the JDBC driver (.jar) version you are using. remember that the jar must be accessible by all hosts in the NiFi cluster.

hi @Zainers, the .jar driver must be accessible on all hosts in the Nifi cluster. the class name must match the driver version, for example: com.cloudera.impala.jdbc.Driver com.cloudera.impala.jdbc4.Driver com.cloudera.impala.jdbc41.Driver the link Boris sent has great examples of how to use and configure it. https://community.cloudera.com/t5/Community-Articles/Connecting-Nifi-to-Impala-using-Simba-JDBC-driver/ta-p/294226

hi @huimin, what error is being returned when accessing HDFS using Trino? i recommend investigating the namenode logs and even the Trino logs to verify the error details.

hi @Boris G, example of an error collected in the impalad log: E0731 04:30:49.177050 59498 authentication.cc:164] SASL message (Kerberos (external)): GSSAPI Error: Unspecified GSS failure. Minor code may provide more information (Clock skew too great) error when trying to connect to impalad with impala-shell: Error connecting: TTransportException, TSocket read 0 bytes Researching this error (Clock skew too great), it's something related to NTP synchronization, but the NTP service is synchronized with KDC (AD), as shown in the chronyd tracking command: Ref time (UTC): Thu Jul 31 12:25:09 2025 Date command: Thu Jul 31 09:25:14 -03 2025 PS: My timezone is -3.

hi @Boris G, we believe the problem is with Impala and not Hue, as the same error is occurring when trying to connect directly to the Impala daemon host with Impala-shell.
