Continuing this lively conversation with myself (hopefully this archived thread may be useful to someone else in the future):
I set the following environment variable as recommended by this page: http://stackoverflow.com/questions/29906686/failed-to-bind-to-spark-master-using-a-remote-cluster-with-two-workers export SPARK_LOCAL_IP=127.0.0.1 Then I got errors related to booting the metastore_db. So I deleted that directory. After that I was able to run spark-shell again. Now let's see if this hack fixes the tests...
