# [DRILL-7787](https://issues.apache.org/jira/browse/DRILL-7787): Apache drill failed to start ## Description It's not a problem. After many tests, drill 1.18 RC can connect to ZK 3.5 cluster. If you want to connect to the old ZK cluster (< 3.5), you can follow the changed document below. ## Documentation Start from Drill 1.18, ZK version is upgraded to 3.5.7. So by default, we can't connect to the old ZK cluster (< 3.5). If we need to use the previous ZK, let's do this: first, delete the zookeeper dependency files in ${DRILL_HOME}/jars/ext, then copy zookeeper-3.4.x.jar to the directory, and finally restart the cluster. ## Testing 1. By default, drill cluster can be started. (ZK 3.5) 2. After replaced the new client with zookeeper-3.4.x.jar, you can also start the drill cluster. ---------------------------------------------------------------- This is an automated message from the Apache Git Service.
