Michael Armbrust created SPARK-2650: ---------------------------------------
Summary: 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)
