Matei Zaharia created SPARK-1879:
------------------------------------
Summary: 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
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.
