[jira] [Updated] (DRILL-2789) Query fails when text-specific syntax
is used on non-text formats.
[ https://issues.apache.org/jira/browse/DRILL-2789?page=com.atlassian.jira.plugin.system.issuetabpanels:all-tabpanel ]
Abhishek Girish updated DRILL-2789:
-----------------------------------
Description:
When a user specifies a query which is valid on Text formats (CSV), but invalid on other formats, the query fails with an IllegalArgumentException, which is not clear.
*Parquet:*
{code:sql}
> select * from catalog_sales where columns[3] is not null limit 1;
