Apache Spark reassigned SPARK-18122: ------------------------------------ Assignee: Apache Spark > Fallback to Kryo for unknown classes in ExpressionEncoder > --------------------------------------------------------- > > Key: SPARK-18122 > URL: https://issues.apache.org/jira/browse/SPARK-18122 > Project: Spark > Issue Type: Improvement > Components: SQL > Affects Versions: 2.0.1 > Reporter: Michael Armbrust > Assignee: Apache Spark > Priority: Critical > > In Spark 2.0 we fail to generate an encoder if any of the fields of the class > are not of a supported type. One example is {{Option\[Set\[Int\]\]}}, but > there are many more. We should give the user the option to fall back on > opaque kryo serialization in these cases for subtrees of the encoder, rather > than failing. -- This message was sent by Atlassian JIRA (v6.3.4#6332) --------------------------------------------------------------------- To unsubscribe, e-mail: issues-unsubscr...@spark.apache.org For additional commands, e-mail: issues-h...@spark.apache.org
