Summary: The coordinator should avoid distributing query fragments
to exception nodes.
Key: IMPALA-10599
URL: https://issues.apache.org/jira/browse/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.
