------------------------------------
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
https://gist.github.com/nasokan/531b4ff9bf827d0835ab
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.
