             Summary: DataFrame and JDBC regression
                 Key: SPARK-8386
                 URL: https://issues.apache.org/jira/browse/SPARK-8386
             Project: Spark
          Issue Type: Bug
          Components: SQL
    Affects Versions: 1.4.0
         Environment: RHEL 7.1
            Reporter: Peter Haumer
            Priority: Critical


I have an ETL app that appends to a JDBC table new results found at each run.  In 1.3.1 I did this:

testResultsDF.insertIntoJDBC(CONNECTION_URL, TABLE_NAME, false);

When I do this now in 1.4 it complains that the "object" 'TABLE_NAME' already exists. I get this even if I switch the overwrite to true.  I also tried this now:

testResultsDF.write().mode(SaveMode.Append).jdbc(CONNECTION_URL, TABLE_NAME, connectionProperties);

getting the same error. It works running the first time creating the new table and adding data successfully. But, running it a second time it (the jdbc driver) will tell me that the table already exists. Even SaveMode.Overwrite will give me the same error.
