> Key: IMPALA-8858
> URL: https://issues.apache.org/jira/browse/IMPALA-8858
> Project: IMPALA
> Issue Type: Bug
> Reporter: Andrew Sherman
> Assignee: Bikramjeet Vig
> Priority: Major
> Fix For: Impala 3.4.0
>
>
> The metrics provided in [IMPALA-8806] are useful but there is not a way to
> see how many executor groups are idle.
> Please add a metric which measures the number of executor groups that are
> both healthy and idle.
> It is OK to for this to be 0 for a short time for example when an executor
> group is created.
> This should be part of the new "cluster-membership" metric group.
