-------------------------------
Summary: FairScheduler: totalMaxShare is not calculated correctly
in computeSharesInternal
Key: YARN-2534
URL: https://issues.apache.org/jira/browse/YARN-2534
Project: Hadoop YARN
Issue Type: Bug
Components: scheduler
Affects Versions: 2.5.0
Reporter: zhihai xu
Assignee: zhihai xu
Fix For: 2.6.0
FairScheduler: totalMaxShare is not calculated correctly in
computeSharesInternal for some cases.
If the sum of MAX share of all Schedulables is more than Integer.MAX_VALUE ,but
each individual MAX share is not equal to Integer.MAX_VALUE. then totalMaxShare
will be a negative value, which will cause all fairShare are wrongly calculated.
