Subject [jira] Created: (HADOOP-3296) Some levels are skipped while creating the task cache in JobInProgress

Some levels are skipped while creating the task cache in JobInProgress
----------------------------------------------------------------------

                 Key: HADOOP-3296
                 URL: https://issues.apache.org/jira/browse/HADOOP-3296
             Project: Hadoop Core
          Issue Type: Bug
          Components: mapred
    Affects Versions: 0.17.0
            Reporter: Amar Kamat
            Priority: Blocker
             Fix For: 0.17.0


Consider the following piece of code
{code:title=JobInProgress.createCache()|borderStyle=solid}
Node node = jobtracker.resolveAndAddToTopology(host);
for (int j = 0; j < maxLevel; j++) {
          node = JobTracker.getParentNode(node, j);
          .....
{code}
With {{maxLevel = 5}} the caches will be created in the following order
||j||node-level||
|0|0|
|1|1|
|2|3|
|3|6|
which is not as desired.
