I'm trying to configure ssh for the Hadoop mapreduce, but my nodes only
communicate with each others using RSA keys in pem format.

(It doesn't work)
ssh user@host
Permission denied (publickey).

(It works)
ssh -i ~/key.pem user@host

The nodes in mapreduce communicate using ssh. How I configure the ssh, or
the mapreduce to work with the pem file.

You need to configure ssh to use your pem files, by default it uses dsa or
rsa files.  Look at man ssh_config.

Hi,

Nodes in Hadoop do not communicate using SSH. See
http://wiki.apache.org/hadoop/FAQ#Does_Hadoop_require_SSH.3F
