             Summary: mapWithState + async operations = no checkpointing
                 Key: SPARK-23474
                 URL: https://issues.apache.org/jira/browse/SPARK-23474
             Project: Spark
          Issue Type: Bug
          Components: DStreams
    Affects Versions: 2.2.1
            Reporter: Daniel Lanza García


In my Spark Streaming job I use mapWithState which obligates me to enable checkpointing. A job is trigger in each batch by the operation: stream.foreachRDD(rdd.foreachPartition()).

Under this situation the job was checkpoinitng every 10 minutes (batches of 1 minute).

Now, I have changed the output operation to async: stream.foreachRDD(rdd.foreachPartitionAsync()).

But checkpointing is not taking place... I tried checkpointing the RDD which I map with state, it get checkpointed but does not break the lineage so tasks keeps growing with every batch.
