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.

[--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) Command to execute on Master Node

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.
