Subject [jira] [Commented] (DRILL-4305) Querying folders broken in 1.4.0
Date Thu, 04 Feb 2016 11:38:39 GMT

    [ https://issues.apache.org/jira/browse/DRILL-4305?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=15132193#comment-15132193

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:: https://mail-archives.apache.org/mod_mbox/drill-user/201601.mbox/browser

> 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
