Querying a directory of json.gz Files in Drill 1.4

[Holy Alexander]

I keep my JSON Files in local File system, such as

D:\DataFiles\2015\12\16\2015-12-16T0000.json.gz
D:\DataFiles\2015\12\16\2015-12-16T0100.json.gz
D:\DataFiles\2015\12\16\2015-12-16T0200.json.gz
(etc.)

Up to Drill 1.3
SELECT * FROM ` D:\DataFiles\2015\12\16` ORDER BY ID LIMIT 10
would produce the desired result, querying all the files in the directory.


In Drill 1.4 the same Query
SELECT * FROM ` D:\DataFiles\2015\12\16` ORDER BY ID LIMIT 10

always results in this error:
org.apache.drill.common.exceptions.UserRemoteException: VALIDATION ERROR: 
Unexpected internal error near index 1 \ ^ [Error Id: 
467e9ccd-3730-4add-aa63-a205a1e16107 on ... ]

However,
SELECT * FROM ` D:\DataFiles\2015\12\16\2015-12-16T0000.json.gz ` ORDER BY ID 
LIMIT 10
Still successfully queries a single file in Drill 1.4

I was searching the doc for changes in Drill 1.4 but could not find a hint what 
goes wrong?

Any clues?

Thanks,
Alexander
