David Morávek commented on FLINK-23840:
---------------------------------------
I think we may go even a bit further and warn user if configured checkpoint
storage is not used, eg. because the legacy state Backend took precedence.

>
>
> After the refactoring of the state backends and checkpoint storage done in
> 1.13, some folks who were using either the filesystem state backend or the
> rocksdb state backend find themselves accidentally using
> JobManagerCheckpointStorage (because it is the default), and then are very
> confused by this error message:
>
> {{throw new IOException(}}
> {{ "Size of the state is larger than the maximum permitted memory-backed
> state. Size="}}
> {{ + size}}
> {{ + " , maxSize="}}
> {{ + maxSize}}
> {{ + " . Consider using a different state backend, like the File System State
> backend.");}}
> This should instead say something like
> {quote}Consider using FileSystemCheckpointStorage instead.
