Hi,
I am running a Beam Pipeline on Flink 1.2 and facing an issue in
restoring a job from checkpoint. If I modify my beam pipeline to add a
new operator and try to restore from the externalized checkpoint, I get
the error
/java.lang.IllegalStateException: Invalid Invalid number of operator
states. Found :56. Expected: 58//
// at
org.apache.flink.util.Preconditions.checkState(Preconditions.java:195)//

From the savepoint guide [1], new operator added should be initialized
without any state. Any idea why this error is reported.
Also note, I am not setting a ID to my operator ( because Flink runner
in Beam does set the operator name user provided in pipeline creation)
