---------------------------------

             Summary: The coordinator should avoid distributing query fragments to exception nodes.
                 Key: IMPALA-10599

             Project: IMPALA
          Issue Type: Improvement
          Components: Distributed Exec
    Affects Versions: Impala 3.4.0, Impala 3.2.0
         Environment: LSB Version: core-4.1-amd64
Distributor ID: CentOS
Description: CentOS release 7.4.1708.7
Release: 7.4.1708.7
impala version: 3.2.0
            Reporter: zhi tang


When I join[shuffle] with unbalanced fields, there will be data-skewed nodes during execution.This will result in the skewed node being under high load for a long time, because the query is likely to be endless.If other queries are committed or running during this time, they may be rejected or an exception thrown.
