Yu Li closed FLINK-19172.
-------------------------
Resolution: Not A Problem
In Flink we use the code convention that method parameters are non-null unless
marked with {{@Nullable}} annotation, which also applies to the
{{AbstractFileStateBackend#validatePath}} method. And we could see the
[caller|https://github.com/apache/flink/blob/master/flink-runtime/src/main/java/org/apache/flink/runtime/state/filesystem/AbstractFileStateBackend.java#L109-L110]
of this method follows this rule.
Please feel free to reopen the issue if you have any other concerns
[~alessiosavi]. Thanks.
