title: Mac spark-shell Error initializing SparkContext
body: <p>I tried to start spark 1.6.0 (spark-1.6.0-bin-hadoop2.4) on Mac OS Yosemite 10.10.5 using </p>
  
  <pre><code>"./bin/spark-shell". 
  </code></pre>
  
  <p>It has the error below. I also tried to install different versions of Spark but all have the same error. This is the second time I'm running Spark. My previous run works fine. </p>
  
  <pre><code>log4j:WARN No appenders could be found for logger (org.apache.hadoop.metrics2.lib.MutableMetricsFactory).
  log4j:WARN Please initialize the log4j system properly.
  log4j:WARN See http://logging.apache.org/log4j/1.2/faq.html#noconfig for more info.
  Using Spark's repl log4j profile: org/apache/spark/log4j-defaults-repl.properties
  To adjust logging level use sc.setLogLevel("INFO")
