Apache Spark commented on SPARK-5841: ------------------------------------- User 'srowen' has created a pull request for this issue: https://github.com/apache/spark/pull/4648 > Memory leak in DiskBlockManager > ------------------------------- > > Key: SPARK-5841 > URL: https://issues.apache.org/jira/browse/SPARK-5841 > Project: Spark > Issue Type: Bug > Components: Block Manager > Affects Versions: 1.2.1 > Reporter: Matt Whelan > Assignee: Matt Whelan > Fix For: 1.3.0 > > > DiskBlockManager registers a Runtime shutdown hook, which creates a hard > reference to the entire Driver ActorSystem. If a long-running JVM repeatedly > creates and destroys SparkContext instances, it leaks memory. > I suggest we deregister the shutdown hook if DiskBlockManager.stop is called. > It's redundant at that point. > PR coming. > See also > http://mail-archives.apache.org/mod_mbox/spark-user/201501.mbox/%3CCA+kjH+w_DDTEBE9XB6NrPxLTUXD=nc_d-3ogxtumk_5v-e0...@mail.gmail.com%3E -- 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
