STORM-918 Storm CLI could validate arguments/print usage
Storm commands that mandate proper args to be passed would now throw
the function's doc string as help rather than exiting out with error after
creating the JVM
process.
Example :
./storm kill
Syntax: [storm kill topology-name [-w wait-time-secs]]
Kills the topology with the name topology-name. Storm will
first deactivate the topology's spouts for the duration of
the topology's message timeout to allow all messages currently
being processed to finish processing. Storm will then shutdown
the workers and clean up their state. You can override the length
of time Storm waits between deactivation and shutdown with the -w flag.
./storm get-errors
Syntax: [storm get-errors topology-name]
Get the latest error from the running topology. The returned result
contains
the key value pairs for component-name and component-error for the
components in error.
The result is returned in json format.
