[jira] [Created] (IMPALA-10270) Failed Task Blacklisting

Wenzhe Zhou created IMPALA-10270:
------------------------------------

             Summary: Failed Task Blacklisting
                 Key: IMPALA-10270
                 URL: https://issues.apache.org/jira/browse/IMPALA-10270
             Project: IMPALA
          Issue Type: Sub-task
          Components: Backend
            Reporter: Wenzhe Zhou
            Assignee: Wenzhe Zhou


* 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
