             Summary: zkcli script put/putfile should allow overwriting an 
existing znode's data
                 Key: SOLR-6397
                 URL: https://issues.apache.org/jira/browse/SOLR-6397
             Project: Solr
          Issue Type: Bug
            Reporter: Timothy Potter


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.solr.cloud.ZkCLI.main(ZkCLI.java:268)


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