             Summary: Spark Data Frame Fails to Load Postgres Tables with JSONB DataType Columns
                 Key: SPARK-7869
                 URL: https://issues.apache.org/jira/browse/SPARK-7869
             Project: Spark
          Issue Type: Bug
          Components: PySpark, SQL
    Affects Versions: 1.3.1, 1.3.0
         Environment: Spark 1.3.1
            Reporter: Brad Willard
            Priority: Minor


Most of our tables load into dataframes just fine with postgres. However we have a number of tables leveraging the JSONB datatype. Spark will error and refuse to load this table. While asking for Spark to support JSONB might be a tall order in the short term, it would be great if Spark would at least load the table ignoring the columns it can't load or have it be an option.
