             Summary: Jar upload directory not created
                 Key: FLINK-6541
                 URL: https://issues.apache.org/jira/browse/FLINK-6541
             Project: Flink
          Issue Type: Bug
    Affects Versions: 1.2.0
            Reporter: Andrey


Steps to reproduce:
* setup configuration property: jobmanager.web.tmpdir = /mnt/flink/web
* this directory should not exist
* Run flink job manager.
* in logs: 
{code}
2017-05-11 12:07:58,397 ERROR org.apache.flink.runtime.webmonitor.WebMonitorUtils           - WebServer could not be created [main]
java.io.IOException: Jar upload directory /mnt/flink/web/flink-web-3f2733c3-6f4c-4311-b617-1e93d9535421 cannot be created or is not writable.
{code}

Expected:
* create parent directories if they do not exit. i.e. use "uploadDir.mkdirs()" instead of "uploadDir.mkdir()"

Note:
* BlobServer create parent directories (See BlobUtils storageDir.mkdirs())
