Jacek Lewandowski created SPARK-3009:
----------------------------------------
Summary: ApplicationInfo doesn't get initialised after
deserialisation during recovery
Key: SPARK-3009
URL: https://issues.apache.org/jira/browse/SPARK-3009
Project: Spark
Issue Type: Bug
Components: Spark Core
Affects Versions: 1.0.1
Reporter: Jacek Lewandowski
The {{readObject}} method has been removed from {{ApplicationInfo}} so that it
does not initialise its transient fields properly after deserialisation. It
follows throwing NPE during recovery of an application in
{{MetricSystem.registerSource}}. As [~andrewor14] said, he removed
{{readObject}} method by accident.
