Josh Rosen updated SPARK-7689: ------------------------------ Labels: releasenotes (was: ) > Remove TTL-based metadata cleaning (spark.cleaner.ttl) > ------------------------------------------------------ > > Key: SPARK-7689 > URL: https://issues.apache.org/jira/browse/SPARK-7689 > Project: Spark > Issue Type: Sub-task > Components: Spark Core > Reporter: Josh Rosen > Assignee: Apache Spark > Labels: releasenotes > > With the introduction of ContextCleaner, I think there's no longer any reason > for most users to enable the MetadataCleaner / {{spark.cleaner.ttl}} (except > perhaps for super-long-lived Spark REPLs where you're worried about orphaning > RDDs or broadcast variables in your REPL history and having them never get > cleaned up, although I think this is an uncommon use-case). I think that > this property used to be relevant for Spark Streaming jobs, but I think > that's no longer the case since the latest Streaming docs have removed all > mentions of {{spark.cleaner.ttl}} (see > https://github.com/apache/spark/pull/4956/files#diff-dbee746abf610b52d8a7cb65bf9ea765L1817, > for example). > See > http://apache-spark-user-list.1001560.n3.nabble.com/is-spark-cleaner-ttl-safe-td2557.html > for an old, related discussion. Also, see > https://github.com/apache/spark/pull/126, the PR that introduced the new > ContextCleaner mechanism. > For Spark 2.0, I think we should remove {{spark.cleaner.ttl}} and the > associated TTL-based metadata cleaning code. -- 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
