tar -xzf hama-0.3.0-incubating.tar.gz

Don't forget to chown the directory as the same user you configured Hadoop in the step before.

...

This mode is the default mode if you download Hama (>= 0.3.0) and install it. When submitting a job it will run a local multithreaded BSP Engine on your server. It can be configured via the "bsp.master.address" property to "local". You can adjust the number of threads used in this utility by setting the "bsp.local.tasks.maximum" property. See the Settings step how and where to configure this.

...

This mode is when you just have a single server and want to launch all the deamon processes (BSPMaster, Groom and Zookeeper). It can be configured when you set the "bsp.master.address" to a host address, e.G. "localhost" and put the same address into the "groomservers" file in the configuration directory. As stated it will run a BSPMaster, a Groom and a Zookeeper on your machine.

...

This mode is just like the "Pseudo Distributed Mode", but you have multiple machines, which are mapped in the "groomservers" file.

Settings

• BSPMaster and Zookeeper settings - Figure out where to run your HDFS namenode and BSPMaster. Set the variable bsp.master.address to the BSPMaster's intended host:port. Set the variable fs.default.name to the HDFS Namenode's intended host:port.
