[jira] [Created] (SPARK-26728) Make rdd.unpersist and
broadcast.unpersist blocking configurable
liupengcheng created SPARK-26728:
------------------------------------
Summary: Make rdd.unpersist and broadcast.unpersist blocking configurable
Key: SPARK-26728
URL: https://issues.apache.org/jira/browse/SPARK-26728
Project: Spark
Issue Type: Improvement
Components: Spark Core
Affects Versions: 2.4.0, 2.1.0
Reporter: liupengcheng
Currently, rdd.unpersist's blocking argument is set to true by default. However, in actual production cluster(especially large cluster), node lost or network issue can always happen.
Users always use rdd.unpersist as non-exceptional, so sometimes the blocking unpersist may cause user's job failure, and this happened many times in our cluster.

I think we can make this blocking argument as a config, so that we can control the default value of it with gray scale systems.
