[jira] [Commented] (FLINK-16724) ListSerializer cannot serialize
list which containers null
[ https://issues.apache.org/jira/browse/FLINK-16724?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=17072596#comment-17072596 ]
Congxian Qiu(klion26) commented on FLINK-16724:
-----------------------------------------------
[~nppoly] thanks for report this issue, This is not the problem of {{ListSerialzier}}, the reason is that {{LongSerialzier}} does not support serializer null value. if you want to serializer null values, you can use {{NullableSerializer instead of }}{{LongSerializer}}.
Currently, you will still find that the test will fail if you replace {{LongSerializer}} with {{NullableSerializer}}because the implementation of {{NullableSerializer}}#copy is not correct, I've created FLINK-16916 to track it.
