      Description

      I have an issue where I try to load more than one file into a dataframe using a wildcard e.g.
      %pyspark
      df = sqlContext.read.json("/jsonfiles/*.json")

      throws an exception (stack trace at end). Whereas the following succeeds:

      df = sqlContext.read.json("/jsonfiles/namedfile.json")

      stack trace:

      Py4JJavaError: An error occurred while calling o147.json.
