maxActiveApplications(|PerUser) per queue is too low for small clusters
-----------------------------------------------------------------------
Key: MAPREDUCE-3784
URL: https://issues.apache.org/jira/browse/MAPREDUCE-3784
Project: Hadoop Map/Reduce
Issue Type: Bug
Components: mrv2
Affects Versions: 0.23.1
Reporter: Ramya Sunil
We ran into this issue while testing on small clusters.
On a 7node cluster with 8G per node, for a queue with absolute capacity 30%,
user limit 100%, maxActiveApplications and maxActiveApplicationsPerUser is
calculated to be 1.
This means that even though the queue has 17GB(0.3*8*7), only 1 user can run 1
app at a given time queuing up rest of the apps/users. This hurts performance
on small clusters.
