Michael Armbrust updated SPARK-2650: ------------------------------------ Target Version/s: 1.1.0 > Wrong initial sizes for in-memory column buffers > ------------------------------------------------ > > Key: SPARK-2650 > URL: https://issues.apache.org/jira/browse/SPARK-2650 > Project: Spark > Issue Type: Bug > Components: SQL > Affects Versions: 1.0.0, 1.0.1 > Reporter: Michael Armbrust > Assignee: Cheng Lian > Priority: Critical > > The logic for setting up the initial column buffers is different for Spark > SQL compared to Shark and I'm seeing OOMs when caching tables that are larger > than available memory (where shark was okay). > Two suspicious things: the intialSize is always set to 0 so we always go with > the default. The default looks like it was copied from code like 10 * 1024 * > 1024... but in Spark SQL its 10 * 102 * 1024. -- This message was sent by Atlassian JIRA (v6.2#6252)
