Description

zkcli doesn't allow me to update a znode that already exists, perhaps using a -f (force) flag?

Currently, if I want to putfile for a znode that already exists, results in:

Exception in thread "main" org.apache.zookeeper.KeeperException$NodeExistsException: KeeperErrorCode = NodeExists for /clusterstate.json
at org.apache.zookeeper.KeeperException.create(KeeperException.java:119)

The workaround is to use ZooKeeper's command-line set command with "`cat <file>`"
