Jimmy Xiang commented on HIVE-10473:
------------------------------------
If the new value is null, the set will fail at Configuration#set(String name,
String value, String source), which checks to make sure neither name or value
to be null.
> Spark client is recreated even spark configuration is not changed

> Currently, we think a spark setting is changed as long as the set method is
> called, even we set it to the same value as before. We should check if the
> value is changed too, since it takes time to start a new spark client.
