https://github.com/apache/drill/pull/517
If I have some extra time to set this up on a Mac or Linux, I will. That's
not so convenient at the moment. Besides, this should work on Windows,
shouldn't it? I noticed that there's an RpcException coming in from the server
side (the drill-bit), but the exception includes nothing like a stack trace to
figure out where it's failing. How can I debug the server side? Is there a
log file? Or which source file can I change to catch the exception on server
side, and log a stack trace?
Regarding the 7th test, yes I added it. I tried a fresh git clone to
Windows from apache/drill master, and that TestDecimal (with 6 tests) fails
exactly the same way. It does appear to have something to do with the
different newline convention on Windows (CR-LF), but I need something like a
server-side stack trace to localize the problem. I tried hacking
TestDecimal.java to change all \n to \r\n (CR LF) in the query string that is
sent to the server (Windows only), but that did not help.

unfortunately, I don't have access to a windows machine. I would suggest a
few options:
1. I just noticed that your test run shows 7 tests. Mine had 6 tests. I
suppose you added a new one. Can you first try a clean version without your new
test ?
2. Could you try it on a different machine with either mac or linux ?
3. Maybe you can seek help from others in the community (I believe
@adityakishore runs on windows + cygwin). —
