Namenode format fails

[subrotosanyal]

Hi @mpdehaan

This is from one of the example present in the Git repo. This looks like a problem with the scripts (not a problem of Ansible framewok).
If I change the permissions manually for the file /etc/hadoop/conf.empty/mapred-site.xml and re-execute the scripts; every thing works nicely. I would say this isn't a hadoop issue.

I see the issue is closed; please confirm if the issue is really fixed or an invalid.

Cheers,

Hi Subroto,

We will have a look at the issue, can you let us know which version of
ansible and what distribution of os you are using for this installation
and also can you check the permission on the
/etc/hadoop/conf.empty/mapred-site.xml.

Also can you set:

• name: Copy the hadoop configuration files
  template: src=roles/common/templates/hadoop_ha_conf/{{ item }}.j2
  dest=/etc/hadoop/conf/{{ item }} mode=0644

in https://github.com/ansible/ansible-examples/blob/master/hadoop/roles/hadoop_primary/tasks/hadoop_master.yml

and see if that helps.

Regards,
Benno Joy

Hi @bennojoy ,
Ansible Version:

Subroto:dap subroto$ ansible --version
ansible 1.3.4

OS Distribution:

[subroto@ip-10-143-182-148 Datameer-3.1.0-cdh4.4-mr1]$ lsb_release -a
LSB Version:    :core-4.0-amd64:core-4.0-noarch:graphics-4.0-amd64:graphics-4.0-noarch:printing-4.0-amd64:printing-4.0-noarch
Distributor ID: CentOS
Description:    CentOS release 6.2 (Final)
Release:    6.2
Codename:   Final

Permission of the file:

[root@ip-10-143-182-148 ~]# ls -l /etc/hadoop/conf.empty
total 60
-rw-r--r-- 1 root root 1335 Sep  3 22:48 configuration.xsl
-rw-r--r-- 1 root root 1001 Nov 12 07:03 core-site.xml
-rw-r--r-- 1 root root 2489 Nov 12 07:03 hadoop-metrics.properties
-rw-r--r-- 1 root root 1773 Nov 12 07:03 hadoop-metrics2.properties
-rw-r--r-- 1 root root 9196 Sep  3 22:48 hadoop-policy.xml
-rw-r--r-- 1 root root 3730 Nov 12 07:03 hdfs-site.xml
-rw-r--r-- 1 root root 8735 Sep  3 22:48 log4j.properties
-rw------- 1 root root 3752 Nov 12 07:03 mapred-site.xml
-rw-r--r-- 1 root root  125 Nov 12 07:03 slaves
-rw-r--r-- 1 root root 2316 Sep  3 22:48 ssl-client.xml.example
-rw-r--r-- 1 root root 2251 Sep  3 22:48 ssl-server.xml.example

I think the suggested workaround will work but, same needs to done for hadoop_secondary also.

Request the ticket to be re-opened till it is found that the issue is invalid or the issue is fixed.

Cheers,

yup-- I had already replied above that this ticket was closed in error, had thought it was filed on ansible/ansible, and then deleted the errant comment about the close -- but forgot to reopen! Reopened now, thanks!

@subrotosanyal
can you let us know if the provided detail helps to fix the issue, if so i will update the playbook, PR also welcome :)

[sebgoa]

I am facing this as well, the fix (mode=0644) does not seem to help. I am using ansible 1.5 and targeting hosts with centos 6.5

closing as the hadoop example was removed
