himanshug opened a new pull request #8427: update HRTR to account for task known to be running on a worker when it shows up
URL: https://github.com/apache/incubator-druid/pull/8427
 
 
   When a worker disappears for a short time and re-appears , it might have lost information that it was running some tasks (due to a crash) and does not report task status of those tasks.
   HRTR should take notice of those and mark them failed as is done for Zookeeper based RTR.
