Spark 2.3: python example from the readme gives '"java.lang.IllegalArgumentException"

I use the following versions:

python 2.7.10 pyddq==4.1.1 drunken-data-quality==4.1.1 spark 2.3.0 spark uses scala 2.11.8 java 1.8.0_162

Are there people that are able to run this? I have a feeling that this issue might be due to wrong/conflicting versions.

import os
os.environ['PYSPARK_SUBMIT_ARGS'] = '--jars /Users/vincent/Downloads/drunken-data-quality-assembly_2.11-4.1.1.jar pyspark-shell'
from pyspark.sql import SparkSession
from pyddq.core import Check

sparkSession = SparkSession.builder.appName("example-pyspark-read-and-write").getOrCreate()
df = sparkSession.createDataFrame([(1, "a"), (1, None), (3, "c")])
check = Check(df)
check.hasUniqueKey("_1", "_2").isNeverNull("_1").run()

above test case gives the following error:

Hi @vincentclaes! Can you check if it runs with Spark 2.2?

[FRosner]

It doesn’t support Python 3 at the moment and I’m not actively working on this project right now. If you want, feel free to submit a PR though, we’ll review it asap.
