Florian Koenig created FLINK-4788:
-------------------------------------

             Summary: State backend class cannot be loaded, because fully 
qualified name converted to lower-case
                 Key: FLINK-4788
                 URL: https://issues.apache.org/jira/browse/FLINK-4788
             Project: Flink
          Issue Type: Bug
          Components: State Backends, Checkpointing
    Affects Versions: 1.1.2
         Environment: Debian Linux and Mac OS X
            Reporter: Florian Koenig
            Priority: Blocker


The name of the state backend in the configuration file ist converted to 
lower-case (see 
https://github.com/eBay/Flink/blob/master/flink-streaming-java/src/main/java/org/apache/flink/streaming/runtime/tasks/StreamTask.java#L587).

Therefore, the class cannot be found, and the state backend (e.g., RocksDB) is 
not loaded properly (see 
https://github.com/eBay/Flink/blob/master/flink-streaming-java/src/main/java/org/apache/flink/streaming/runtime/tasks/StreamTask.java#L603).
