[Fab-user] Fabric parallelism error

[chinky gupta]

I am getting a fatal error: Needed to prompt for a connection or sudo password

One or more hosts fail to execute task

While i was trying to achieve parallelism through fabric
I have tried using decorators like @parallel or @runs_ parllel
as well as command line arguments like -P or -z
I am really getting troubled while executing this program..I dont know where does problem really exists.

Waiting for your earlier reply
