Doris Xin created SPARK-2088:
--------------------------------
Summary: 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
Reporter: Doris Xin
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. The following issue is
encountered during serialization:
java.lang.NullPointerException
