Description

When a CTAS command fails for any reason, it should not create the target table. It appears that when the storage output format is JSON, we end up creating an empty table. If the output format is Parquet, this works correctly.

0: jdbc:drill:zk=local> alter session set `store.format` = 'json';
..
0: jdbc:drill:zk=local> create table orders3 as select * from cp.`tpch/orders.parquet` where o_orderdate between '1994-07-01' and '1994-09-31' limit 10;
Query failed: Failure while running fragment. Value 31 for dayOfMonth must be in the range [1,30]

// Now fix the query and re-run :

0: jdbc:drill:zk=local> create table orders3 as select * from cp.`tpch/orders.parquet` where o_orderdate between '1994-07-01' and '1994-09-30' limit 10;

ok

summary

----------------------+

false

Table 'orders3' already exists.

0: jdbc:drill:zk=local> select * from orders3;
