A value for the variable Key Pair File can be set in the AWS CLI config file using the “aws configure set emr.key_pair_file <value>” command.
See ‘aws help’ for descriptions of global parameters.
Synopsis¶

--cluster-id <value>
--key-pair-file <value>
[--command <value>]
Options¶
--cluster-id (string)
Cluster Id of cluster you want to ssh into
--key-pair-file (string)
Private key file to use for login
--command (string)

Examples¶
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.
