[jira] [Created] (MAPREDUCE-3700) If a resource in job.jar start with ./, we cannot get it in the backend

If a resource in job.jar start with ./, we cannot get it in the backend
-----------------------------------------------------------------------

                 Key: MAPREDUCE-3700
                 URL: https://issues.apache.org/jira/browse/MAPREDUCE-3700
             Project: Hadoop Map/Reduce
          Issue Type: Bug
          Components: mrv2
    Affects Versions: 0.23.0
            Reporter: Daniel Dai


When testing Pig on hadoop23, I find if Pig register a script start with ./, it fails. The same script success on 20.x clusters.

For example, here is a resource in job.jar:
jar tvf /var/folders/Rq/RqKCrqeVEoahpTBMcvLV1E+++TI/-Tmp-/Job6041588317527904436.jar|grep scriptingudf
  1656 Thu Jan 19 15:49:42 PST 2012 ./libexec/python/scriptingudf.py

Here is the code we try to get the resource in map:
some_pig_object.class.getResourceAsStream("./libexec/python/scriptingudf.py");

Registering even with absolute path does not work.
