Vladimir Sitnikov commented on CALCITE-2223:
--------------------------------------------
Finally it works. [~vvysotskyi], would you please review? I wonder if you have
"deactivated" rules.
I've performed the following changes in order to get Drill tests running:
{noformat}
- private static final String customHostName = System.getenv("DRILL_HOST_NAME");
+ private static final String customHostName =
System.getProperty("DRILL_HOST_NAME", "localhost");
...
+ -Duser.language=en
+ -Duser.region=US{noformat}
{noformat}
