Executes command logic. Commands invoked in two different environments:

• CLI utility using GridClient connection to interact with cluster.
• Inside Ignite node therefore local node can be used to interact with cluster.

Please, keep in mind that GridClient protocol is obsolete and can be removed in future releases.

Specified by:

Parameters:

cli - Optional grid client instance.

ignite - Optional ignite node.

arg - Command argument.

printer - Results printer.

Returns:
