The original logging is correct - filesystem state backend is actually
memory state backend + filesystem checkpointing. No need to change the logging.
> Filesystem State Backend logged incorrectly

> Key: FLINK-9127
> URL: https://issues.apache.org/jira/browse/FLINK-9127
> Project: Flink
> Issue Type: Bug
> Components: Core
> Affects Versions: 1.3.2, 1.4.2
> Reporter: Scott Kidder
> Priority: Trivial
>
> When using a filesystem backend, the
> '[StateBackendLoader|https://github.com/apache/flink/blob/1f9c2d9740ffea2b59b8f5f3da287a0dc890ddbf/flink-runtime/src/main/java/org/apache/flink/runtime/state/StateBackendLoader.java#L123]'
> class produces a log message stating: "State backend is set to heap memory".
> Example:
> {{2018-04-04 00:45:49,591 INFO
> org.apache.flink.streaming.runtime.tasks.StreamTask - State backend
> is set to heap memory (checkpoints to filesystem
> "hdfs://hdfs:8020/flink/checkpoints")}}
> It looks like this resulted from some copy-pasta of the previous
> case-statement that matches on the memory backend. This bug is also present
> in earlier releases (1.3.2, 1.4.0) of Flink in the 'AbstractStateBackend'
> class.
> This log statement should be corrected to indicate that a filesystem backend
> is in use.
