?????? loading native library in hive UDF

[Xiaobin]

Thank you Kumar, It works!  
How about the second Question: I add an archive file (*.tar.gz) by using ADD 
ARCHIVE *.tar.gz, it seems that this file is not unarchived automatically. I am 
also confused.

Hi,

Maybe you can try adding native libraries (*.so)&nbsp;files along with its all 
dependent libs (*.so) in


hadoop-{version}/lib/native


$ld libcustom.so --&gt; should show all shared libs resolved from 
local&nbsp;hadoop-{version}/lib/native folder


Above path is shared across the hadoop ecosystem and make sure to add 
so&nbsp;with its all dependent libs on all nodes .

Hi, all:
I'm a beginner of hive. Recently I want to implement a UDF in hive and this 
function is code with java but call some method written in C++. So my UDF need 
to load some native libraries (*.so). I have already added the so to hive by 
using Add file *.so. But it seems that hive doesn't add these so to the 
LD_LIBRARY_PATH automatically, thus, UDF throws 'no so in java.library.path' 
exception. I have almost searched the whole internet but got nothing 
helpful.&nbsp; Have you got any idea of this?


By the way, I add an archive file (*.tar.gz) by using ADD ARCHIVE *.tar.gz, it 
seems that this file is not unarchived automatically. I am also confused.


Thank you.


Best
