Patrick Wendell updated SPARK-2088: ----------------------------------- Priority: Critical (was: Major) > NPE in toString when creationSiteInfo is null after deserialization > ------------------------------------------------------------------- > > Key: SPARK-2088 > URL: https://issues.apache.org/jira/browse/SPARK-2088 > Project: Spark > Issue Type: Bug > Affects Versions: 1.0.0 > Reporter: Doris Xin > Assignee: Doris Xin > Priority: Critical > > After deserialization, the transient field creationSiteInfo does not get > backfilled with the default value, but the toString method, which is invoked > by the serializer, expects the field to always be non-null.
