Description

Consider the following piece of code

JobInProgress.createCache()

Node node = jobtracker.resolveAndAddToTopology(host);
for (int j = 0; j < maxLevel; j++) {
          node = JobTracker.getParentNode(node, j);
          .....

With maxLevel > 2 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.
