Unable to resolve the operator from the metafile using State Processor API

[Partha Mishra <pa...@man-es.com>]

Hi,

I have specified operator uuid for all of my operator in Flink job and triggered a savepoint and `_metafile` got generated. When I use state processor APIs to read the saved snapshot and try to read the mapping, I am not able to resolve which operator id map to which operator in my code.

1.       Is there a way to find it?

2.      What is the hashing technique for the operator id?


Below is the generated savepoint mapping when trying to read from the State Processor APIs - but I am not able to resolve `d7741f4a6cdf388e747557749a0f0d21` corresponds to which operator? If I  know the hashing logic, it becomes easier for me to get the same.
