[jira] [Created] (FLINK-3357) Drop JobId.toShortString()

Stephan Ewen created FLINK-3357:
-----------------------------------

             Summary: Drop JobId.toShortString()
                 Key: FLINK-3357
                 URL: https://issues.apache.org/jira/browse/FLINK-3357
             Project: Flink
          Issue Type: Bug
          Components: Core
    Affects Versions: 0.10.1
            Reporter: Stephan Ewen
             Fix For: 1.0.0


There are several places that use JobId.toShortString() instead of the full JobID, for unique directories, etc.

I think we should drop that method.
  - If the short String representation (8 bytes) is statistically "unique enough", then it is wrong in the first place that the unique IDs have 16 bytes
  - If 16 bytes were chosen with a purpose, then using the short string representation in paths, etc, is clearly violating the guarantees the IDs try to give,

For purely informational logging, it may be a nice util, bit it seems to encourage wrong use.
