Finding out installed packages in Spark
include the package anyway to be sure eg via spak submit:
  $SPARK_HOME/bin/spark-shell --packages graphframes:graphframes:0.1.0-spark1.6
I have been at it for some time and tried everything. 
I need to find out whether the package GraphFrames is included in the spark installation at my office cluster. I am using Spark version 1.5.0. 
Is there a way to list all the installed packages in Spark?
