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:
