> Hive ignore table name character case, transfer table name to lowercase in
> metastore, while Counters/TezCounters are character case sensitive. This
> difference may lead to table statistic collection failed, as when Hive
> collection table statistic based on Counters, and hive use table name as the
> group name of counter.
> ctas.q is an example, during the INSERT OVERWRITE TABLE sql execution, table
> name contains uppercase characters, Hive gather table statistic in
> FileSinkOperator with uppercase table name(translated from sql), and
> aggregate table statistic in StatsTask with lowercase table name(from
> metastore), which would failed table statistic collection.
