When I am installing knapsack can I just install the plugin into 1 node, the load balancer node. Or do I have to install it to all nodes in order to use the feature.
Thanks,

For knapsack export/import, one client node is enough, and then send the request to this node. You can even start a new node with node.data:false and node.master:false, and after the job is done, the node can be stopped and removed.

I am reading the documentation why is it recommended to stop and remove the node containing knapsack once finished? My use case would be that I am going to be shipping this elk stack and need to retrieve data from a client. So they need a convenient way to send me their data.

Then just let knapsack run all the time, and forget about the note.
Other people might be worried about installing, maintaining, and running a community plugin all the time, they can easily remove it by running a tiny separate node on demand.

This is probably another issue but when I run the install command I run into this issue:
```
./bin/plugin --install -u http://xbib.org/repository/org/xbib/elasticsearch/plugin/elasticsearch-knapsack/2.0.0-rc1.0/elasticsearch-knapsack-2.0.0-rc1.0-plugin.zip
Usage:
-u, --url [plugin location] : Set exact URL to download the plugin from
-i, --install [plugin name] : Downloads and installs listed plugins [*]
-t, --timeout [duration] : Timeout setting: 30s, 1m, 1h... (infinite by default)
-r, --remove [plugin name] : Removes listed plugins
-l, --list : List installed plugins
-v, --verbose : Prints verbose messages
-s, --silent : Run in silent mode
-h, --help : Prints this help message
[*] Plugin name could be:
elasticsearch/plugin/version for official elasticsearch plugins (download from download.elasticsearch.org)

You want to install a knapsack 2.x plugin into an ES 1.x node?
