[jira] [Comment Edited] (SPARK-14521) StackOverflowError in Kryo
when executing TPC-DS Query27
[ https://issues.apache.org/jira/browse/SPARK-14521?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=15249012#comment-15249012 ]
Rajesh Balamohan edited comment on SPARK-14521 at 4/20/16 12:31 AM:
--------------------------------------------------------------------
Update:
- By default, spark-thrift server disables "spark.kryo.referenceTracking" (if not specified in conf).
https://github.com/apache/spark/blob/master/sql/hive-thriftserver/src/main/scala/org/apache/spark/sql/hive/thriftserver/SparkSQLEnv.scala#L55
- When "spark.kryo.referenceTracking" is set to true explicitly in spark-defaults.conf, query executes successfully. Alternatively, if "spark.sql.autoBroadcastJoinThreshold" can be set to a very low value in order to prevent broacasting (this is done just for verification).
- Recent changes LongHashedRelation could have introduced loops which would need "spark.kryo.referenceTracking=true" in spark-thrift server. I will create a PR for this.
