How can I delete a data node which is not empty in zookeeper?

Question

For deleting a node in zookeeper from command line interface there is a delete command. When I run it, it says:

Node not empty: /testNode

I am using this guide.

Answer 1

The zkCli provides the rmr (deprecated) or deleteall command for this purpose. It will recursively delete all nodes under the path. This command did not appear until version 3.4.0. The documentation link you provided is for version 3.3.3.

Answer 2

deleteall nodeName

For example: deleteall /hbase works for me in hbase 2.4.1

Answer 3

I use the following command in Java:

zkClient.deleteRecursive(ZkUtils.getTopicPath(topicName));
