Hello, I've been getting pretty serious with DC/OS which I guess could be described as a somewhat polished distribution of Mesos. I'm not sure how relevant DC/OS is to this problem.
I am using this pyspark program to test the cassandra connection: http://bit.ly/2eWAfxm (github) I can that the df.printSchema() method is working ok but the df.show() method is breaking with this error: Traceback (most recent call last): File "/mnt/mesos/sandbox/squeeze.py", line 28, in <module> df.show() File "/opt/spark/dist/python/lib/pyspark.zip/pyspark/sql/dataframe.py", line 287, in show File "/opt/spark/dist/python/lib/py4j-0.10.1-src.zip/py4j/java_gateway.py", line 933, in __call__ File "/opt/spark/dist/python/lib/pyspark.zip/pyspark/sql/utils.py", line 63, in deco File "/opt/spark/dist/python/lib/py4j-0.10.1-src.zip/py4j/protocol.py", line 312, in get_return_value py4j.protocol.Py4JJavaError: An error occurred while calling o33.showString.
