> Recently，I made a concurrent kylin query test and found a little bug in QueryMetrics:
> If the initial query to a cube or a project is concurrent,  the QueryMetric will register failed and throw a MetricsException.
> The exception is like this:
> "exception":"Metrics source kylin_test,sub=xxxxxxx already exists!"
