-------------------------------

             Summary: use Files.createDirectories instead of directory.mkdirs
                 Key: FLINK-9631
                 URL: https://issues.apache.org/jira/browse/FLINK-9631
             Project: Flink
          Issue Type: Improvement
          Components: Java API
    Affects Versions: 1.4.2, 1.5.0
         Environment: flink1.4

jdk1.8 latest

linux 2.6
            Reporter: makeyang
            Assignee: makeyang


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?
