Hi everyone,
Recently I failed to run a Flink job when enabling RocksDBStateBackend on
the branch master and 1.10.
The exception stack trace is:
The program finished with the following
exception:org.apache.flink.client.program.ProgramInvocationException:
The main method caused an error: The adapter does not support this
method

It seems that this is a BUG. Does anyone encounter such a problem?
I am wondering why we introduce ReadableConfigToConfigurationAdapter
to wrap the Configuration but leave many of the methods in it to throw
UnsupportedOperationException that causes problems.
