------------------------------------

             Summary: Don't reuse avros on SparkPipeline cache()
                 Key: CRUNCH-569
                 URL: https://issues.apache.org/jira/browse/CRUNCH-569
             Project: Crunch
          Issue Type: Bug
          Components: Spark
    Affects Versions: 0.12.0
            Reporter: Nithin Asokan


A cached PCollection/PTable built by Avros using SparkPipeline seem to reuse avro objects. Here is a test that shows this behavior

I would expect the output of this program to create a pair with same key, value. However, this produces Pair with different key value. I have tested this with text file input source and it works as expected. Removing cache() produces expected result.
