[jira] [Updated] (SPARK-20164) AnalysisException not tolerant of
null query plan
[ https://issues.apache.org/jira/browse/SPARK-20164?page=com.atlassian.jira.plugin.system.issuetabpanels:all-tabpanel ]
Kunal Khamar updated SPARK-20164:
---------------------------------
Description:
The query plan in an `AnalysisException` may be `null` when an `AnalysisException` object is serialized and then deserialized, since `plan` is marked `@transient`. Or when someone throws an `AnalysisException` with a null query plan (which should not happen).
`def getMessage` is not tolerant of this and throws a `NullPointerException`, leading to loss of information about the original exception.
The fix is to add a `null` check in `getMessage`.
was:When someone throws an AnalysisException with a null query plan (which ideally no one should), getMessage is not tolerant of this and throws a null pointer exception, leading to loss of information about original exception.
