StephenZou updated SPARK-22243:
-------------------------------
Attachment: CheckpointTest.scala
the reproducible demo
> job failed to restart from checkpoint
> -------------------------------------
>
> Key: SPARK-22243
> URL: https://issues.apache.org/jira/browse/SPARK-22243
> Project: Spark
> Issue Type: Bug
> Components: Spark Core
> Affects Versions: 2.1.0, 2.2.0
> Reporter: StephenZou
> Attachments: CheckpointTest.scala
>
>
> My spark-defaults.conf has an item related to the issue, I upload all jars in
> spark's jars folder to the hdfs path:
> spark.yarn.jars hdfs:///spark/cache/spark2.2/*
> Streaming job failed to restart from checkpoint, ApplicationMaster throws
> "Error: Could not find or load main class
> org.apache.spark.deploy.yarn.ExecutorLauncher". The problem is always
> reproducible.
> I examine the sparkconf object recovered from checkpoint, and find
> spark.yarn.jars are set empty, which let all jars not exist in AM side. The
> solution is spark.yarn.jars should be reload from properties files when
> recovering from checkpoint.
> attach is a demo to reproduce the issue.
