Summary: Investigate RETRY_FAILED_QUERIES with System Tables
Key: IMPALA-12951
URL: https://issues.apache.org/jira/browse/IMPALA-12951
Project: IMPALA
Issue Type: Task
Reporter: Michael Smith
My theory is that {{RETRY_FAILED_QUERIES}} doesn't work well with querying
System Tables because coordinators don't get added to a blacklist when they
fail, so it reschedules them on the same set of nodes.
Look into whether issues with {{RETRY_FAILED_QUERIES}} when a coordinator
restarts (without graceful shutdown) are unique to coordinators, and how to
improve it.
