> Stats of non native tables are inaccurate, thus queries over non native
> tables can not optimized by stats optimizer.
> Take example of query
> {code}
> Explain select count(*) from (select `__time` from druid_test_table limit 1)
> as src ;
> {code}
> the plan will be reduced to
> {code}
> POSTHOOK: query: explain extended select count(*) from (select `__time` from
> druid_test_table limit 1) as src
> POSTHOOK: type: QUERY
> STAGE DEPENDENCIES:
> Stage-0 is a root stage
> STAGE PLANS:
> Stage: Stage-0
> Fetch Operator
