             Summary: LP Bug: 1342954 - LLVM library is not thread-safe and T2 wants to use it as if it were
                 Key: TRAFODION-452
                 URL: https://issues.apache.org/jira/browse/TRAFODION-452
             Project: Apache Trafodion
          Issue Type: Bug
            Reporter: Apache Trafodion
            Assignee: Apache Trafodion
            Priority: Critical


The LLVM library is known to not be thread-safe.    The T2 driver environment wants to have multiple threads in the same process that are using the LLVM library concurrently.   We must either disable the Native Expressions feature when using T2  or  find a way to prevent the LLVM library from being used by more than one thread in a process in a concurrent fashion.   (Assuming, of course, that the open-source group that maintains the LLVM library will not be making the library thread-safe.)
