[jira] [Created] (IMPALA-6002) Impala should install an LLVM diagnostic handler

Tim Armstrong created IMPALA-6002:
-------------------------------------

             Summary: Impala should install an LLVM diagnostic handler
                 Key: IMPALA-6002
                 URL: https://issues.apache.org/jira/browse/IMPALA-6002
             Project: IMPALA
          Issue Type: Sub-task
          Components: Backend
    Affects Versions: Impala 2.11.0
            Reporter: Tim Armstrong
            Priority: Critical


LLVM has an interface to install a diagnostic handler to handle errors. The default behaviour will exit the process immediately, which is not desirable if the problem is something like a malformed IR UDF.  See IMPALA-5999 for an example.
