I have been trying to alter the current state case class (scala) which has 250 variables, now when I add 10 more variables to the class, and when I run my flink application from the save point taken before(Some of the variables are object which are also maintained as state). It fails to migrate the state error : "The new state typeSerializer for operator state must not be incompatible. "
Please suggest what I can do to avoid that error -- Sent from: http://apache-flink-user-mailing-list-archive.2336050.n4.nabble.com/
