Rohith Sharma K S commented on YARN-3053:
-----------------------------------------

[~varun_saxena] would you create sub task ? I see YARN-5647 has both reader and 
collector modifications. Would you separate it out? 
One doubt on HBase communication. Since collectors and readers connect to 
HBase, all the NM and RM need to be configured with HBase keytabs, correct?
