-------------------------------------------
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.
