Re: Create Function with .ll file

Hi Zuo,
  We can't really help without more details.

Did you get any messages in your impalad logs? Any hs_err_pid*.log files?

How did you produce the ll file? It should be an LLVM 3.3 bitcode file for
recent release of Impala.

答复: Create Function with .ll file

["WANG Zuo (王佐)" <wa...@wanda.cn>]

Hi, Tim

I did’t see any impalad logs related to the error.
Here is my change in be/src/udf_samples/CMakeLists.txt.  I compiled aes-deencrypt.cc to libaes-deencrypt.so and aes-deencrypt.ll. But now the .so file is OK but .ll file crashed my impalad.
set(CRYPTOPP_INCLUDE_DIR "/home/dev/Impala/cryptopp")
set(CRYPTOPP_LIBS "/home/dev/Impala/cryptopp/libcryptopp.a")
include_directories(${CRYPTOPP_INCLUDE_DIR})
add_library(aes-deencrypt SHARED aes-deencrypt.cc)
add_dependencies(aes-deencrypt thrift-deps)
target_link_libraries(aes-deencrypt ${CRYPTOPP_LIBS})

COMPILE_TO_IR(aes-deencrypt.cc )
add_dependencies(aes-deencrypt-ir thrift-deps)
target_link_libraries(aes-deencrypt-ir ${CRYPTOPP_LIBS})


Best Regards,
Zuo

I wrote a UDF, it works with .so file, but fail with .ll file. Could anybody help me on this?

I ran below commands in impala-shell. It works fine.
create function aes_decrypt(string,string) returns string location '/user/xxx/libaes- deencrypt.so' symbol='AES_Decrypt';
select aes_decrypt(unhex('CBA4ACFB309839BA426E07D67F23564F'), '1234567890123456');

But when I ran below commands. It crashed my impalad.
create function aes_decrypt_ir(string,string) returns string location '/user/xxx/aes-deencrypt.ll' symbol='AES_Decrypt';
select aes_decrypt_ir(unhex('CBA4ACFB309839BA426E07D67F23564F'), '1234567890123456');
