Hi Matt,
Here are some tasks that call the same notify and it happened that these
files might got changed during the same run.
- name: creates hadoop .sh config files
template: src={{ item }}.j2 dest=/etc/hadoop/conf.{{ nameservice_id }}/{{
item }} owner=hdfs group=hadoop mode=0755
with_items:
- hadoop-env.sh
- yarn-env.sh
tags:
- cdh5_datanode
- cdh5_datanode_conf
- cdh5_datanode_conf_sh
- cdh5_mrv1_slave
notify: reload datanode
- name: create /etc/default/hadoop-hdfs-datanode
template: src=hadoop-hdfs-datanode.j2
dest=/etc/default/hadoop-hdfs-datanode owner=root group=root mode=0644
tags:
- cdh5_datanode
- cdh5_datanode_conf
- cdh5_mrv1_slave
notify: reload datanode
Currently, I already finished my setup and I just do not have the outputs
around but please trust me on this one or you can simply experiment with
something similar to this situation.
Thank you very much,
Steven.
