[jira] Updated: (HADOOP-3296) Some levels are skipped while
creating the task cache in JobInProgress
[ https://issues.apache.org/jira/browse/HADOOP-3296?page=com.atlassian.jira.plugin.system.issuetabpanels:all-tabpanel ]
Amar Kamat updated HADOOP-3296:
-------------------------------
Description:
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 > 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.
