EMR Cluster "Error provisioning instances"

Trying to start EMR cluster following "Getting Started" documentation also tried "Create a Cluster With Spark", but the cluster creation stays 1 hour, 5 minutes in "Starting" status and then fails with:

  • Terminated with errors Internal error
  • Master Instance Group: Error provisioning instances
  • Master - 1: Error provisioning instances

I tried different EMR releases emr-5.9.0 - emr-5.6.0

Solution

  • I were trying to create EMR cluster in EU (Ireland) region and it was failing, when I changed region to EU (Frankfurt) it was created successfully. Don't know why, maybe AWS bug.
