---------------------------------
Summary: Fix nodemgr native compilation problems on FreeBSD9
Key: YARN-1327
URL: https://issues.apache.org/jira/browse/YARN-1327
Project: Hadoop YARN
Issue Type: Bug
Components: nodemanager
Affects Versions: 3.0.0
Reporter: Radim Kolar
Assignee: Radim Kolar
Fix For: 2.2.1, 3.0.0
There are several portability problems preventing from compiling native
component on freebsd.
1. libgen.h is not included. correct function prototype is there but linux
glibc has workaround to define it for user if libgen.h is not directly
included. Include this file directly.
2. query max size of login name using sysconf. it follows same code style like
rest of code using sysconf too.
3. cgroups are linux only feature, make conditional compile and return error if
mount_cgroup is attempted on non linux OS
4. do not use posix function setpgrp() since it clashes with same function from
BSD 4.2, use equivalent function. After inspecting glibc sources its just
shortcut to setpgid(0,0)
These changes makes it compile on both linux and freebsd.
