Is there a way to only run one task in ansible playbook?
For example, in roles/hadoop_primary/tasks/hadoop_master.yml. I have "start hadoop job tracker services" task. Can I just run that one task?
hadoop_master.yml file:
# Playbook for Hadoop master servers
- name: Install the namenode and jobtracker packages
apt: name={{item}} force=yes state=latest
with_items:
- hadoop-0.20-mapreduce-jobtracker
- hadoop-hdfs-namenode
- hadoop-doc
- hue-plugins
- name: start hadoop jobtracker services
service: name=hadoop-0.20-mapreduce-jobtracker state=started
