Hi all, I used Whirr to boot up an AWS cluster with Hama, as suggested in the documentation [1].
It installed Hama version 0.4.0, is it the expected behaviour? Also, the default Whirr configuration creates a master node, along with 5 slave nodes. Is it necessary to have a dedicated master? I was planning to configure a single instance (need to install some additional software), and then create AMI from that and clone several times, thus avoid configuring each node. In this symmetric scheme I need to install the master (hadoop-jobtracker+hama-master+…) and slave (hadoop-tasktracker+hama-groomserver+…) software to each node; will it work? Thanks in advance, Roman [1] http://wiki.apache.org/hama/LaunchHamaUsingWhirr
