Re: Problem regarding UDF

[Mohan Agarwal <mo...@gmail.com>]

Hi Edward,
 I didn't get any file called ".hiverc" in Hive installation directory,
where I can put my all commands which can be executed on starting hive. Even
I search on Internet for ".hiverc" but didn't get any right conclusion.
    Please help me to solve this problem.

Thanking You
Mohan Agarwal
