             Summary: Thrift generated Python/Java code doesn't get regenerated when deleted
                 Key: IMPALA-13604
                 URL: https://issues.apache.org/jira/browse/IMPALA-13604
             Project: IMPALA
          Issue Type: Bug
          Components: Infrastructure
    Affects Versions: Impala 4.5.0
            Reporter: Joe McDonnell


Thrift generated Python code lives in shell/gen-py. If someone deletes shell/gen-py and then runs "make shell_tarball", it will fail because the directory and Thrift-generated code doesn't get regenerated. This is also true for Thrift-generated Java code. shell_tarball does depend on gen-deps, which would be able to generate those files, but gen-deps doesn't actually know which files are associated with Python or Java.

The CMake code that generates Thrift knows a little bit about which files are generated for C++, but it does not have similar logic for Java or Python. If we could provide the expected file names in common/thrift/CMakeLists.txt, then it should be able to regenerate those files if they are deleted.
