Description

A simple query like this:
create table `ttt` partition by (r_regionkey) as select * from cp.`tpch/region.parquet`;

Without touching generated data from CTAS, this query select * from `ttt`; works.

Then, I tried to reorganize the parquet generated by CTAS as:

-----Q1/ ... .pq Q2/ ... .pq Q3/ ... .pq

However, after this manual moving, any query fails. Surprisingly, even after I manually move the data to the original place, the queries which worked before all failed with:

Error: PARSE ERROR: From line 1, column 15 to line 1, column 19: Table 'ttt' not found
