             Summary: Avoid or eliminate expensive YARN get all applications 
call
                 Key: SLIDER-1168
                 URL: https://issues.apache.org/jira/browse/SLIDER-1168
             Project: Slider
          Issue Type: Bug
    Affects Versions: Slider 0.91
            Reporter: Gour Saha


YARN get all applications call will prove to be very costly in a cluster with 
hundreds or thousands of Slider apps running. We need to come up with a 
strategy to avoid or eliminate these expensive calls. This would mean that the 
application id needs to be stored in Slider's state store in HDFS. This is 
specifically more critical when Slider Client calls are made from a service 
like the YARN native REST API service (YARN-4793).
