# [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.
