-------------------------------------
Summary: Creating a UDF from a shared library with a .ll extension
crashes Impala
Key: IMPALA-6008
URL: https://issues.apache.org/jira/browse/IMPALA-6008
Project: IMPALA
Issue Type: Bug
Components: Backend
Affects Versions: Impala 2.9.0, Impala 2.8.0, Impala 2.10.0
Reporter: Tim Armstrong
Priority: Critical
{code}
create function foo (string, string) returns string location
'/test-warehouse/thisIsReallyASharedObject.ll' symbol='MyAwesomeUdf';
{code}
A create function statement like the one above can crash Impala if the file is
actually an ELF shared object.
I encountered this on a cluster I have access to. I haven't confirmed whether
*any* .so can crash Impala or whether it requires a .so with specific
characteristics.
