> Project: Flink
> Issue Type: Improvement
> Components: Runtime / State Backends
> Affects Versions: 1.4.2, 1.5.0

> 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?
