Tim Armstrong resolved IMPALA-811.
----------------------------------
Resolution: Won't Fix
Good idea, but too open ended to be actionable
> add metrics identifying communication errors
> --------------------------------------------
>
> Key: IMPALA-811
> URL: https://issues.apache.org/jira/browse/IMPALA-811
> Project: IMPALA
> Issue Type: Improvement
> Components: Distributed Exec
> Affects Versions: Impala 1.2.3
> Reporter: Chris Leroy
> Priority: Minor
> Labels: observability
>
> This is a request for metrics in the various Impala processes that count
> communication failures between components.
> I'd love to see counters for Impala Daemon errors communicating with HDFS,
> other Impala Daemons, the Catalog Server, the State Store, etc. Ditto for the
> State Store and Catalog Server's communications.
> I realize this is a slightly open ended request. I'm happy to help identify a
> specific list of communication targets if I can be of help.
