             Summary: Querying folders broken in 1.4.0
                 Key: DRILL-4305
                 URL: https://issues.apache.org/jira/browse/DRILL-4305
             Project: Apache Drill
          Issue Type: Bug
          Components: Functions - Drill
    Affects Versions: 1.4.0
         Environment: Local Embedded Drill 1.4.0 Version running on Windows 10 
and Java 8 
            Reporter: Andre Pomp
             Fix For: 1.3.0


Hey all,

today I updated drill 1.3.0 to 1.4.0 and I explored that querying folders 
(using the Syntax of 1.3.0) is not possible anymore. 

So on Drill 1.3.0 the following sqline command was possible:

SELECT * FROM dfs.`C:\Users\someuser\Desktop\testdir`;
Moreover, I also tested queries like 

SELECT * FROM dfs.`C:\Users\someuser\Desktop\testdir\`;
SELECT * FROM dfs.`C:\Users\someuser\Desktop\testdir\*`;
SELECT * FROM dfs.`C:\Users\someuser\Desktop\testdir\*.json`;

All those commands work fine with Drill 1.3.0. 
However, when switiching to 1.4.0, I get the following Exceptions:

Error: VALIDATION ERROR: Unexpected internal error near index 1
\
 ^

Can someone explain why the old queries are not working anymore on 1.4.0? How 
can I query folders with 1.4.0?
Currently, I assume that there is a bug.

Best regards,
André
