[jira] [Created] (IMPALA-11605) IMPALA-9999's upgrade of flatbuffers to 1.12 causes a conflict with Hive

             Summary: IMPALA-9999's upgrade of flatbuffers to 1.12 causes a conflict with Hive
                 Key: IMPALA-11605
                 URL: https://issues.apache.org/jira/browse/IMPALA-11605
             Project: IMPALA
          Issue Type: Bug
          Components: Infrastructure
    Affects Versions: Impala 4.2.0
            Reporter: Joe McDonnell


IMPALA-9999's upgrade to GCC 10.4 switched to flatbuffers 1.12 as older flatbuffers versions do not compile on newer GCC versions. This required switching the Java version as well. However, upgrading the Java version causes a conflict with Hive, which uses flatbuffers 1.9.

Since Impala is upgrading in order to avoid the C++ compilation issue, we can resolve the conflict by using flatbuffers 1.9 and patching it with the fix from here: [https://github.com/google/flatbuffers/commit/86153fd7405ad3bae28aee7f5affdbeb2d77e533]
