---------------------------------
Summary: Slider should make resource normalization configurable
for app-owners
Key: SLIDER-1201
URL: https://issues.apache.org/jira/browse/SLIDER-1201
Project: Slider
Issue Type: Bug
Components: appmaster
Affects Versions: Slider 0.91
Reporter: Gour Saha
Slider currently by default normalizes all resource requests which exceeds max
allowed in the cluster.
{code}
2016-11-02 07:24:47,722 [main] WARN state.AppState - Resource requirements of
LLAP normalized from <memory:186368, vCores:1> to <memory:143616, vCores:1>
{code}
This behavior should be made configurable. It will allow app owners to choose
if they want normalization and the app to continue running with reduced
resources (as default), OR if they do not want normalization and want the app
to fail right away, rather than several days later when it actually tries to
use as much memory it had requested, but never got. This causes a debugging
nightmare as well, trying to figure out why the app was even killed by YARN
when it exceeded the resource usage.
