Let's keep the default behavior static constructor (which uses trivial) and
then we don't have to update the constructor everywhere.
> Hive query hangs with limit 0 clause
> ------------------------------------
>
> Key: DRILL-3623
> URL: https://issues.apache.org/jira/browse/DRILL-3623
> Project: Apache Drill
> Issue Type: Bug
> Components: Storage - Hive
> Affects Versions: 1.1.0
> Environment: MapR cluster
> Reporter: Andries Engelbrecht
> Fix For: Future
>
>
> Running a select * from hive.table limit 0 does not return (hangs).
> Select * from hive.table limit 1 works fine
> Hive table is about 6GB with 330 files with parquet using snappy compression.
> Data types are int, bigint, string and double.
> Querying directory with parquet files through the DFS plugin works fine
> select * from dfs.root.`/user/hive/warehouse/database/table` limit 0;
