> Key: FLINK-9631
> URL: https://issues.apache.org/jira/browse/FLINK-9631
> Project: Flink
> Issue Type: Improvement
> Components: Runtime / State Backends
> Affects Versions: 1.4.2, 1.5.0
> Environment: flink1.4
> jdk1.8 latest
> linux 2.6
> Reporter: makeyang
> Priority: Not a Priority
> Labels: auto-deprioritized-minor, auto-unassigned
>
> 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?
