Summary: Cannot load a Pipeline Model on a stopped Spark Context Key: SPARK-32534 URL: https://issues.apache.org/jira/browse/SPARK-32534 Project: Spark Issue Type: Bug Components: Deploy, Kubernetes Affects Versions: 2.4.6 Reporter: Kevin Van Lieshout I am running Spark in a Kubernetes cluster than is running Spark NLP using the Pyspark ML Pipeline Model class to load the model and then transform on the spark dataframe. We run this within a docker container that starts up a spark context, mounts volumes, spins up executors, etc and then does it transformations, udfs, etc and then closes down the spark context. The first time I load the model when my service has just been started, everything is fine. If I run my application for a second time without resetting my service, even though the context is entirely stopped from the previous run and a new one is started up, the Pipeline Model has some attribute in one of its base classes that thinks the context its running on is closed, so then I get a : cannot call a function on a stopped spark context when I try and load the model in my service again. I have to shut down my service each time if I want consecutive runs through my spark pipeline, which is not ideal, so I was wondering if this was a common issue amongst fellow pyspark users that use Pipeline Model, or is there a common work around to resetting all spark contexts or whether the pipeline model caches a spark context of some sort. Any help is very useful. cls.pipeline = PipelineModel.read().load(NLP_MODEL) is how I load the model. And our spark context is very similar to a typical kubernetes/spark setup.
