Running the ACO 420 Hadoop VM on OSX Yosemite running VMware Fusion 7 and later

Notes, 2-13-2015
  1. You have to run the .vmx file directly.
  2. You need to let VMware Fusion upgrade the file.
  3. Ignore the errors, but do not wake up the suspended machine, don't resume and discard.
  4. After it's shut down and powered off, up the RAM to 8 GB and make sure compatibility is set to all the way.
  5. Once you have the VM running, messing with the BASHRC file, running aliases, and adding exports won't affect the setup, EXCEPT $HADOOP_HOME. Do not enable $HADOOP_HOME or $HADOOP_PREFIX; create softlinks (ln [path] targetname) instead.
  6. Once you have started hadoop, if you open the jobtracker web page and it shows 0 for the nodes, check the status. If it says INITIALIZING, hadoop is still booting up. After the status changes to RUNNING, you should then see 1 for the nodes. If not, the hadoop installation is corrupt.
