             Summary: Unify backend tests into a single executable
                 Key: IMPALA-8070
                 URL: https://issues.apache.org/jira/browse/IMPALA-8070
             Project: IMPALA
          Issue Type: Bug
          Components: Infrastructure
    Affects Versions: Impala 3.2.0
            Reporter: Joe McDonnell


Each backend test links in all of our libraries, so each backend test executable is ~400MB. Impala has 100+ backend test executables and this number will only grow, so this means a fully built Impala development environment will have 40GB of backend tests. Relinking these backend tests also takes a significant chunk of time.

We should explore linking the backend tests into a single executable and using gtest_filter to run individual tests from that executable. This would reduce the diskspace requirement as well as the link time for backend tests.

This is an umbrella Jira to track tasks associated with this change.
