>             Project: Flink
>          Issue Type: Improvement
>          Components: Runtime / State Backends

>         Environment: flink1.4
> jdk1.8 latest

> job can't be run due to below exception:
> {color:#6a8759}Could not create RocksDB data directory{color}
>  but with this exception, I can't tell exactly why.
> so I suggest Files.createDirectories which throw exception be used rather than File.mkdirs
>  
> I have some more suggestions:
>  # should we use Files.createDirectories to relpace File.mkdirs?
>  # each time task manager throw exception to jobmanager, should IP+nodeId be contained in exception, which means we should define more flink exception which is used to wrap other exceptions such as jdk exceptions?
