-----------------------------------
Summary: container-executor: possible -1 return value of fork() is
not always checked
Key: YARN-10018
URL: https://issues.apache.org/jira/browse/YARN-10018
Project: Hadoop YARN
Issue Type: Bug
Components: nodemanager
Reporter: Peter Bacsko
Assignee: Peter Bacsko
There are some places in the container-executor native, where the {{fork()}}
call is not handled properly. This operation can fail with -1, but sometimes
the necessary if branch is missing to validate the success.
Also, at one location, the return value is defined as an {{int}}, not
{{pid_t}}. It's better to handle this transparently and change it.
