Description

When creating a UDF via the CREATE FUNCTION command, Impala will always attempt to mangle the functions symbol in a .so file, even if the symbols aren't mangled. This leads to errors like:

ERROR: AnalysisException: Could not find function AddUdf(INT, INT) in: hdfs://quickstart.cloudera:8020/user/hive/udfs/pepimpala.so
Check that symbol and argument types are correct.

 Unable to find _Z6AddUdfPN10impala_udf15FunctionContextERKNS_6IntValES4_
dlerror: /var/lib/impala/udfs/xxxx.2671.0.so: undefined symbol: _Z6AddUdfPN10impala_udf15FunctionContextERKNS_6IntValES4_
