Joel J commented on DRILL-4305:
-------------------------------
Just confirming I'm seeing the same thing.
1) Each file can be queried individually.
2) One file in a folder works fine.
3) Two individually working files error show the following error message:
Error: VALIDATION ERROR: Unexpected internal error near index 1
I am querying a collection of standardised CSV files, using Windows 10 x64 and
JDK 8u71. There is also another documented case here::

> 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
