Description

« Hide

The Katta command line tool provides the option listNodes, but does not provide an option to remove nodes which are not used anymore (i. e. test nodes). One can remove these nodes with the Zookeeper command line tool. But it would be useful to have such an option with the Katta command line tool.

The patch adds the option "removeNode <index name>" to the Katta command line client.

Indeed, this is not a major feature. But I don't know how to change the priority of an issue already created.

What happens in the case you're removing live node ?

The live node remains active, but queries are not served to it anymore.

The patch just cleans up the Zookeeper. It's up to the Katta administrator to stop the node. Usually a node fails or is permanently removed from the Katta cluster, but remains registered in Zookeeper.

I can also implement a node interaction command to shutdown a live node, if it should be removed. Would that makes sense?
