>                 URL: https://issues.apache.org/jira/browse/FLINK-9300
>             Project: Flink
>          Issue Type: Improvement
>          Components: Runtime / State Backends
>    Affects Versions: 1.4.2
>            Reporter: Kenneth William Krugler
>            Priority: Minor
>
> Currently in the {{MemCheckpointStreamFactory.checkSize()}} method, it can throw an {{IOException}} via:
> {code:java}
> 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.");{code}
> But this will happen even if you’re using the File System State backend.
> This came up here: [https://stackoverflow.com/questions/50149005/ioexception-size-of-the-state-is-larger-than-the-maximum-permitted-memory-backe]
> We could change the message to be:
> {quote}Please consider increasing the maximum permitted memory size, increasing the task manager parallelism, or using a non-memory-based state backend such as RocksDB.
