This is a weird issue. I've been setting hive CLI headers for a long time using
the following:
set hive.cli.print.header=true;
Recently, I started using custom Hive UDF. Here is my test file, myfunc.sql:
--
add jar <myjar>;
create temporary function <myfunc> as <appropriate path>;
<test query 1>;
<test query 2>;
--
This works just fine. However, if I add the line hive cli header to the top,
Hive crashes at line 2, i.e. the create temporary function with the following
error:
--
Added /home/somejar.jar to class path
Added resource: /home/somejar.jar
OK
Exception in thread "main" java.lang.NullPointerException

Any idea what's going on?
