Amazon Elastic Map Reduce - Creating a job flow

This is the fix that worked for me and which you may need if your job flows are reporting the following error:

Last State Change: No active keys found for user account

When you create an AWS account, by default, the security access key has to be created for you. In some cases it will not be created automatically, so you should create one by yourself following these steps:

• Under the menu accessed by clicking your account name from within the AWS Console you will find a Security Credentials option. Click on it

• Expand the Access Keys (Access Key ID and Secret Access Key) section. Check if there is a key already created there.

• If no key found, then click on Create new access key and make it active (it should be set to active by default).

• Now create a job flow and it should work

I too had the same problems following the AWS tutorials creating my first AWS EMR Cluster.The new AWS EMR console would try to create the cluster "Starting" but then after 2-4 mins the cluster status would change to "Terminated with errors : Validation error" and looking at the cluster details it said status "No active keys found for user account".

You must create an active access key in your security Credentials as advised above.Then it worked fine for me.
