Michael Smith commented on IMPALA-11326:
----------------------------------------
Turns out our tests use {{/jsonmetrics?json}}, which returns the raw JSON input
rather than looking up the template.
> Legacy /jsonmetrics endpoint fails in dev build
> -----------------------------------------------

> Key: IMPALA-11326
> URL: https://issues.apache.org/jira/browse/IMPALA-11326
> Project: IMPALA
> Issue Type: Bug
> Components: Frontend
> Affects Versions: Impala 2.7.0
> Reporter: Michael Smith
> Priority: Minor
>
> Querying the webserver's {{/jsonmetrics}} endpoint results in
> {code}
> $ curl localhost:25000/jsonmetrics
> Could not open template: /home/michael/Impala//www//legacy-metrics.tmpl
> {code}
> https://github.com/apache/impala/commit/0c2a71576fb2954ca97d4f8225a60b93eab8594a
> changed how that endpoint is served, but didn't add {{legacy-metrics.tmpl}}.
> Since no one's filed a bug on this in the 6 years since 2.7.0 was released,
> maybe that endpoint can be removed. However it's possible that other
> packaging adds {{legacy-metrics.tmpl}} so it's usable outside of development.
