grycap / ansible-role-hadoop Goto Github PK

Hi,
There is a problem in the task "Set JAVA_HOME in hadoop-env.sh" on Ubuntu trusty.
The console log:

` TASK [grycap.hadoop : Set JAVA_HOME in hadoop-env.sh] **************************************************************************************************************************
fatal: [10.6.14.40]: FAILED! => {"msg": "No file was found when using with_first_found. Use the 'skip: true' option to allow this task to be skipped if no files are found"}
to retry, use: --limit @/Users/Zsomx/hadoop-installer---ansible/hadoop_namenode.retry

PLAY RECAP *********************************************************************************************************************************************************************
10.6.14.40 : ok=9 changed=7 unreachable=0 failed=1 `

My playbook is a simple one:
`- hosts: hadoop_namenode
become: yes
vars:
namenode_ip: 10.6.14.40
version: '2.9.0'
roles:

• { role: 'grycap.hadoop', hadoop_master: '{{namenode_ip}}', hadoop_type_of_node: 'master', hadoop_version: '{{version}}' } `

Any suggestions?

Thanks!

The step

• command: "{{ hadoop_home }}/bin/hdfs namenode -format creates=/tmp/hadoop-root/dfs/name"
  when: (hadoop_type_of_node == 'master') or (hadoop_type_of_node == 'namenode')

Uses as test the "/tmp/hadoop-root/dfs/name" directory, instead of the one provided in the hdfs_props collection (dfs.datanode.data.dir)

Hello ¿ could you write a simple example to create a playbook for 1 master and 1 node (sharing datanode, resourcenode, etc), in order to check if your ansible role works? Without ansible-galaxy?

- hosts: hadoop_namenode
   become: yes
   vars:
       namenode_ip: 192.168.10.10
       datanode_ip: 192.168.10.10
       version: '2.8.0'
   roles:
      { role: 'grycap.hadoop', hadoop_master: '{{namenode_ip}}', hadoop_type_of_node: 'master', hadoop_version: '{{version}}' }
      { role: 'grycap.hadoop', hadoop_master: '{{datanode_ip}}', hadoop_version: '{{version}}' }

Regards.
