Note
To use the following examples, you must have the AWS CLI installed and configured. See the Getting started guide in the AWS CLI User Guide for more information.
Unless otherwise stated, all examples have unix-like quotation rules. These examples will need to be adapted to your terminal’s quoting rules. See Using quotation marks with strings in the AWS CLI User Guide .
The following command opens an ssh connection with the master instance in a cluster with the cluster ID j-3SD91U2E1L2QX:
aws emr ssh --cluster-id j-3SD91U2E1L2QX --key-pair-file ~/.ssh/mykey.pem
The key pair file option takes a local path to a private key file.
Output:
ssh -o StrictHostKeyChecking=no -o ServerAliveInterval=10 -i /home/local/user/.ssh/mykey.pem hadoop@ec2-52-52-41-150.us-west-2.compute.amazonaws.com
