    Description

      • If node “a” has a higher rate of task failures compared to the rest of the cluster, then node “a” should be blacklisted
      • There should only be a specific set of failures that count against a node - e.g. query specific failures like reading corrupted files, or mem limit exceeded should not count
      • This is similar to how Spark Executor Blacklisting works
