Amazon Elastic Map Reduce : Listing job flows in command line tools Issue?

I'm new to Amazon web services, I'm trying to run job flows on Amazon elastic map reduce jobs using command line interface tools.

I followed the steps from amazon developer guide of this developer guide from aws.But things are not getting clear to me.

If I execute the command ./elastic-mapreduce --list to list the job flows. Shows the Following error.

Thanks in Advance, and Can anyone Please tell me Why i am getting the above error while listing the job flows.

Solution

  • check the avilable rvm, by using the following command

       $ rvm list

    it will show:

       ruby-1.8.7-p374
   ruby-2.0.0-p247

    then you should specifiy the rvm version, by using the following command

       $ rvm use 1.8.7

    then you can try to list the jobflows . . .
