Subject [jira] [Created] (YARN-5883) Avoid or eliminate expensive YARN get all applications call
Date Tue, 15 Nov 2016 06:59:58 GMT
Gour Saha created YARN-5883:
-------------------------------

             Summary: Avoid or eliminate expensive YARN get all applications call
                 Key: YARN-5883
                 URL: https://issues.apache.org/jira/browse/YARN-5883
             Project: Hadoop YARN
          Issue Type: Sub-task
            Reporter: Gour Saha
             Fix For: yarn-native-services


YARN _getAllApplications()_ call with no param or with application types _getApplications(Set<String>
applicationTypes)_ are very costly in a cluster with hundreds or thousands of Slider apps
running.

YARN now has the API to filter by application tags - YARN-4491. We should be able to use this
to avoid these expensive calls.
