Anyone know if you can queue a different deployment of an M/R from within an M/R itself using task? I seem to recall that you can't use task within M/R but not sure why I'm thinking that. Working on some fun error handling.

i think u can use task module in MR script, use it in summarize stage

I frequently chain multiple M/R scripts together by having one script start the next in the Summarize stage, using the N/task module. Never had any issues with it.

Perfect, thanks!
