Matei Zaharia commented on SPARK-1879: -------------------------------------- BTW the warning on Java 8 is the following: {code} Java HotSpot(TM) 64-Bit Server VM warning: ignoring option MaxPermSize=128m; support was removed in 8.0 {code} Not *that* scary. I think we can live with this for a bit and possibly test java -version in a later release. > Default PermGen size too small when using Hadoop2 and Hive > ---------------------------------------------------------- > > Key: SPARK-1879 > URL: https://issues.apache.org/jira/browse/SPARK-1879 > Project: Spark > Issue Type: Bug > Components: Spark Core > Reporter: Matei Zaharia > Assignee: Matei Zaharia > Priority: Critical > Fix For: 1.0.0 > > > If you launch a spark-shell with Hadoop 2 and Hive on the classpath, and try > to use Hive therein, the PermGen quickly reaches 85 MB after a few commands, > at which point Java gives up and freezes. We should pass a MaxPermSize to > prevent this. Unfortunately passing this results in a warning on Java 8, but > that's still better than not passing it. > I don't think this affects stuff other than the shell; it's just the > combination of Scala compiler + Hive + Hadoop 2 that pushes things over the > edge. -- This message was sent by Atlassian JIRA (v6.2#6252)
