             Summary: Change debug logs in FSDownload.java to info logs for 
better escalations debugging
                 Key: YARN-11353
                 URL: https://issues.apache.org/jira/browse/YARN-11353
             Project: Hadoop YARN
          Issue Type: New Feature
          Components: resourcemanager, yarn
            Reporter: Sanjay Kumar Sahu


AM was stuck in Preparing Local resources step and it timed out and never 
started the driver. This happened in one of the customer's cluster and got 
resolved when this cluster got deleted and the customer started using another 
cluster . The logs were not enough to look into the issue. Adding more info 
logs will help to understand when did the download of the files start and when 
did it end, or whether it actually reached that step like adding the 
containerId here to know who is downloading.
