-------------------------------------------
Summary: FairShare calculation broken for large values after
YARN-8833
Key: YARN-9173
URL: https://issues.apache.org/jira/browse/YARN-9173
Project: Hadoop YARN
Issue Type: Bug
Components: fairscheduler
Affects Versions: 3.3.0
Reporter: Wilfred Spiegelenburg
Assignee: Wilfred Spiegelenburg
After the fix for the infinite loop in YARN-8833 we now get the wrong values
back for fairshare calculations under certain circumstances. The current
implementation works when the total resource is smaller than Integer.MAXVALUE.
When the total resource goes above that value the number of iterations is not
enough to converge to the correct value.
The new test {{testResourceUsedWithWeightToResourceRatio()}} only checks that
the calculation does not hang but does not check the outcome of the calculation.
