NAME
Parallel::MapReduce::Worker::SSH - MapReduce, remote worker via SSH
SYNOPSIS
use Parallel::MapReduce::Worker::SSH;
my $w = new Parallel::MapReduce::Worker::SSH (host => '10.0.10.2');
# otherwise same interface as parent class Parallel::MapReduce::WorkerDESCRIPTION
This subclass of Parallel::MapReduce::Worker implements a remote worker using SSH for launching and the resulting SSH tunnel for communicating.
By default, the package is trying an SSH client /usr/bin/ssh and is assuming that the Perl binary on the remote machine is /usr/bin/perl. Tweak the package variables $SSH and $PERL if these assumptions are wrong.
INTERFACE
Constructor
The construct expects the following fields:
host(default: none)-
At constructor time an SSH connection to the named host is attempted. Then a remote Perl program to implement the worker there is started. For this, obviously
Parallel::MapReducemust be installed on the remote machine.
NOTE: Do not forget to call shutdown on an SSH worker, otherwise you will have a lot of lingering SSH connections.
