> Project: Kylin
> Issue Type: Improvement
> Components: Metrics
> Reporter: Congling Xia
> Assignee: Congling Xia
> Priority: Minor
> Fix For: v3.1.2
>
>
> Users may use simple queries like 'select 1' to check the availability of
> kylin service. No realization is needed for such queries. Metric system will
> raise NullPointerException when trying to get the name of the realization.
> It does not cause the query to fail, but prints a lot of annoying warning
> logs with stack-traces.
