Andy Grove updated ARROW-8254:
------------------------------
Description:
I'm testing the CLI and it appears almost unusable.
We should at least improve the error messages for common errors.
{code:java}
> CREATE EXTERNAL TABLE taxi
STORED AS PARQUET
LOCATION '/mnt/nyctaxi/tripdata.parquet'
;
0 rows in set.
> SELECT COUNT(*) FROM taxi;
General("General(\"Can\\\'t build array reader without columns!\")")
{code}
{code:java}
> SELECT COUNT(*) FROM aggregate_test_100;
ArrowError(InvalidArgumentError("at least one column must be defined to create
a record batch"))
{code}
was:
{code:java}
> SELECT COUNT(*) FROM aggregate_test_100;
ArrowError(InvalidArgumentError("at least one column must be defined to create
a record batch"))
{code}
> [Rust] [DataFusion] CLI is not working as expected
