Apache Spark commented on SPARK-4759: ------------------------------------- User 'andrewor14' has created a pull request for this issue: https://github.com/apache/spark/pull/3633 > Deadlock in complex spark job in local mode > ------------------------------------------- > > Key: SPARK-4759 > URL: https://issues.apache.org/jira/browse/SPARK-4759 > Project: Spark > Issue Type: Bug > Components: Spark Core > Affects Versions: 1.1.1, 1.2.0, 1.3.0 > Environment: Java version "1.7.0_51" > Java(TM) SE Runtime Environment (build 1.7.0_51-b13) > Java HotSpot(TM) 64-Bit Server VM (build 24.51-b03, mixed mode) > Mac OSX 10.10.1 > Using local spark context > Reporter: Davis Shepherd > Assignee: Andrew Or > Priority: Critical > Attachments: SparkBugReplicator.scala > > > The attached test class runs two identical jobs that perform some iterative > computation on an RDD[(Int, Int)]. This computation involves > # taking new data merging it with the previous result > # caching and checkpointing the new result > # rinse and repeat > The first time the job is run, it runs successfully, and the spark context is > shut down. The second time the job is run with a new spark context in the > same process, the job hangs indefinitely, only having scheduled a subset of > the necessary tasks for the final stage. > Ive been able to produce a test case that reproduces the issue, and I've > added some comments where some knockout experimentation has left some > breadcrumbs as to where the issue might be. -- This message was sent by Atlassian JIRA (v6.3.4#6332) --------------------------------------------------------------------- To unsubscribe, e-mail: issues-unsubscr...@spark.apache.org For additional commands, e-mail: issues-h...@spark.apache.org
