Puppet Class: profile::analytics::cluster::users

Defined in:


Class profile::analytics::cluster::users

Installs any special system users needed on all analytics cluster nodes. This is used for ensuring that users exist for use in HDFS. We want uids and gids to be synchronized everywhere. 'service' system users are declared in puppet classes, so only those need to be included here. 'user' system users, which exist to allow human users to sudo and run jobs as that user, are declared in the admin module's data.yaml.

NOTE: Puppet does not manage creation of system user HDFS home directories. you will need to do this manually. To do so, run from any Hadoop node:

sudo -u hdfs hdfs dfs -mkdir /user/$user && \
sudo -u hdfs hdfs dfs -chown $user:$group /user/$user

And optionally:

sudo -u hdfs hdfs dfs -chmod 775 /user/$user
