-----------------------------------
Description:
Git.Commit.ID: f658a3c (Mar 9 2015)
*Convert a simple text file to Parquet:*
{code:sql}
> select * from `abc.dat` limit 1;
+------------+
| columns |
+------------+
| ["hi","abc"] |
+------------+
1 row selected (0.574 seconds)
> create table abc_1 as select cast(columns[0] as varchar(10)) as a from
> `abc.dat`;
+------------+---------------------------+
| Fragment | Number of records written |
+------------+---------------------------+
| 0_0 | 1 |
+------------+---------------------------+
1 row selected (0.626 seconds)
> select * from abc_1 limit 1;
+------------+
| a |
+------------+
| hi |
+------------+
1 row selected (0.135 seconds)
{code}
*Create a view on top of the Parquet table:*
{code:sql}
> create view abc_1 as select cast(a as varchar(10)) as b from abc_1;
+------------+------------+
| ok | summary |
+------------+------------+
| true | View 'abc_1' created successfully in 'dfs.tmp' schema |
+------------+------------+
1 row selected (0.072 seconds)
> select * from abc_1 limit 1;
Query failed: SqlValidatorException: Column 'a' not found in any table
Error: exception while executing query: Failure while executing query.
(state=,code=0)
OR
> create view abc_1 as select cast(a as varchar(10)) as b from dfs.`/tmp/abc_1`;
+------------+------------+
| ok | summary |
+------------+------------+
| true | View 'abc_1' created successfully in 'dfs.tmp' schema |
+------------+------------+
1 row selected (0.047 seconds)
> select * from abc_1 limit 1;
Query failed: SqlValidatorException: Column 'a' not found in any table
Error: exception while executing query: Failure while executing query.
(state=,code=0)

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

1 row selected (0.046 seconds)
> select * from abc_1 limit 1;
+--+
| |
+--+
+--+
No rows selected (11.856 seconds)
{code}
In the third case, queries do not return and need to be cancelled.
For example:
{code:sql}
> use dfs.tpcds1;
+--+
| |
+--+
+--+
No rows selected (2.854 seconds)
{code}
Sqlline needs to be suspended, killed and restarted to be able to query again.
