Amazon Elastic Map Reduce : Command Line Tools installation Issue?

Question

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 to list the job flows. Shows the Following error.

:~/Applications/elastic-mapreduce-ruby$ elastic-mapreduce --list
Error: Request has expired. Timestamp date: 2013-07-09T01:13:42-07:00

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

Answer 1

This problem mostly occurred because of time stamp in the elastic map reduce and your computer is not same. So check the time stamp of both the machines and set the same Time stamps to the machines what u use to run your job flows. Then it would run correctly.
