--------------------------------------
Summary: Drill requires parentheses in the empty file for 'LOAD'
argument in the 'CREATE SCHEMA' command
Key: DRILL-7332
URL: https://issues.apache.org/jira/browse/DRILL-7332
Project: Apache Drill
Issue Type: Bug
Affects Versions: 1.16.0
Reporter: Denys Ordynskiy
Assignee: Arina Ielchiieva
Fix For: 1.17.0
Description:
- created csvh table: {color:#205081}create table dfs.tmp.`test_table` (col1)
as select full_name from cp.`employee.json` limit 3;{color}
- created text file on the local file system `for_load` with text without
parentheses: {color:#14892c}col1 varchar not null{color}
- created some schema file: {color:#205081}create or replace schema *LOAD*
'file:///home/user/for_load' for table dfs.tmp.`test_table` properties
('drill.strict' = 'false');{color} - schema was created successfully;
- remove all text from the `for_load` file and try to create the same schema:
{color:#205081}create or replace schema *LOAD* 'file:///home/user/for_load' for
table dfs.tmp.`test_table` properties ('drill.strict' = 'false');{color}
*Actual result:*
Drill throws an error:
{color:#d04437}Error: RESOURCE ERROR: Unable to parse schema []: Line [1],
position [0], offending symbol [@0,0:-1='<EOF>',<-1>,1:0]: mismatched input
'<EOF>' expecting {'(', ID, QUOTED_ID}
Error while preparing / creating schema for [%s] dfs.tmp.test_table
[Error Id: faad9c09-2e3e-428c-bd7a-6da8832a943b ] (state=,code=0){color}
*Expected result:*
Since Drill doesn't require parentheses for non empty `for_load` file (with
some columns),
It couldn't require parentheses for the empty file, used in the `LOAD` argument.
