[jira] [Created] (DRILL-2827) Allow implicit cast from strings to boolean

Aman Sinha created DRILL-2827:
---------------------------------

             Summary: Allow implicit cast from strings to boolean
                 Key: DRILL-2827
                 URL: https://issues.apache.org/jira/browse/DRILL-2827
             Project: Apache Drill
          Issue Type: Bug
          Components: Functions - Drill
    Affects Versions: 0.8.0
            Reporter: Aman Sinha
            Assignee: Aman Sinha


The following query fails: 
{code}
select * from dfs.`bool.json` where key = 'true';
Error in expression at index -1.  Error: Missing function implementation: [castINT(BIT-REQUIRED)].  Full expression: --UNKNOWN EXPRESSION--..
{code}
The reason is that a prior fix for DRILL-2590 removed the implicit casting from string literals to boolean.  That fix is valid for non-string values.
