Ranger Yarn Plugin Config prevent Yarn NM to start

[ChristopheLRTE]

Hello,

It seems that installing Ranger cause an issue with yarn_nm service.

Indeed, here are the error log :

/************************************************************
SHUTDOWN_MSG: Shutting down NodeManager at bdpnode02.applispfref.sipfref.local/10.132.151.217

The yarn nm service intend to find container-executor.cfg in /etc/hadoop/conf (linked by /opt/tdp/hadoop-3.1.1-TDP-0.1.0-SNAPSHOT/etc/hadoop symlink) folder, whereas after Yarn plugin Ranger config Task (show this : Create symbolic link from etc/hadoop in {{ hadoop_install_dir }} to actual Resourcemanager config dir) finished, it updates the path to /etc/hadoop/conf.rm

As a consequence the command /opt/tdp/hadoop-3.1.1-TDP-0.1.0-SNAPSHOT/bin/container-executor --checksetup does not find anymore the file container-executor.cfg inside the good folder.

Am I wrong or not, please ?

Thank you very much for your advice,
C.L.

Hello !

Could someone help me please ?
This behaviour is reproducible 😞

Thanks
