You can fix this by changing hama.zookeeper.quorum variable 'localhost' to '127.0.0.1'.
2. I get ": Incorrect header or version mismatch from 127.0.0.1:52772 got version 3 expected version 4." while starting.
Please use a release of Hadoop that is compatible with the Hama Release. Please refer to our CompatibilityTable.
3. I get ": FATAL org.apache.hama.BSPMasterRunner: java.net.UnknownHostException: Invalid hostname for server: local" while starting.
This is the case if you're in the local-mode and tried to launch Hama via the start script. In this mode, nothing has to be launched. A multithreaded running utility will start when submitting your job. Please refer to Local Mode
