On a perfectly running HDP3.1 cluster, one time the ATSv2 Timeline Reader stopped responding. Following some guide I've tried refreshing the service by cleaning the configs and restarting it by
yarn app -destroy ats-hbase
After this, restarting the service doesn't help, and starting the service by
yarn app -start ats-hbase
doesn't work, since the config json is missing:
ERROR client.ApiServiceClient: File does not exist: <>/user/yarn-ats/.yarn/services/ats-hbase/ats-hbase.json
What is this .json and how do I get it running again? Where are some example templates of a working .json that I could use? I remember this file existing somewhere on a fresh install, but sadly reinstall of the cluster is not an option. Another thing, trying a fresh install on my laptop VM does not create such json file too -- I guess the reason is that the laptop is too small for enforcing hbase use?
Didn't find anything in the official documentation, so would be thankful for any advice!
