Subject [jira] [Created] (YARN-9172) Correct the typo "DominantResourceCalculator" in CapacityScheduler
Date Thu, 03 Jan 2019 03:42:00 GMT
Zhankun Tang created YARN-9172:

             Summary: Correct the typo "DominantResourceCalculator" in CapacityScheduler
                 Key: YARN-9172
                 URL: https://issues.apache.org/jira/browse/YARN-9172
             Project: Hadoop YARN
          Issue Type: Improvement
            Reporter: Zhankun Tang
            Assignee: Zhankun Tang

The error message is thrown when the number of known resource types is greater than 2, but
a typo in it as below in red color. 

"org.apache.hadoop.yarn.exceptions.YarnRuntimeException: RM uses DefaultResourceCalculator
which used only memory as resource-type but invalid resource-types specified


Use {color:#d04437}DomainantResourceCalculator{color} instead to make effective use of these
at org.apache.hadoop.yarn.server.resourcemanager.scheduler.capacity.CapacityScheduler.initScheduler(CapacityScheduler.java:347)
at org.apache.hadoop.yarn.server.resourcemanager.scheduler.capacity.CapacityScheduler.serviceInit(CapacityScheduler.java:426)"

It should be recommending "DominantResourceCalculator" so that user won't search internet
for the correct value.
