Subject Why does Hadoop need ssh access to master and slaves?
Date Wed, 21 Jan 2009 12:23:31 GMT
Hi all,

we've made our first steps in evaluating hadoop. The setup of 2 VMs as a
hadoop grid was very easy and works fine.

Now our operations team wonders why hadoop has to be able to connect to
the master and slaves via password-less ssh?! Can anyone give us an
answer to this question?

Thanks & Regards
Matthias
