             Summary: Yarn NodeManager OOM Listener Fails Compilation on Ubuntu 18.04
                 Key: YARN-8498
                 URL: https://issues.apache.org/jira/browse/YARN-8498
             Project: Hadoop YARN
          Issue Type: Bug
            Reporter: Jack Bearden


While building this project, I ran into a few compilation errors here. The first one was in this file:

hadoop-yarn-project/hadoop-yarn/hadoop-yarn-server/hadoop-yarn-server-nodemanager/src/main/native/oom-listener/impl/oom_listener_main.c

I am not entirely certain the role the cleanup() function has, however when I replaced cleanup() with free() the compiler complained that it was unnecessary due to &descriptors being non-heap. So I just removed it entirely for now.

At the very end, during the compilation of the OOM test, it fails again:
hadoop-yarn-project/hadoop-yarn/hadoop-yarn-server/hadoop-yarn-server-nodemanager/src/main/native/oom-listener/test/oom_listener_test_main.cc
