-----------------------------------------

             Summary: If hdfs-exclude-file config type already exists then installing DATANODE (e.g. while adding new host) fails 
                 Key: AMBARI-3808
                 URL: https://issues.apache.org/jira/browse/AMBARI-3808
             Project: Ambari
          Issue Type: Bug
          Components: agent
            Reporter: Vitaly Brodetskyi
            Assignee: Vitaly Brodetskyi
            Priority: Critical


Error:
{code}
Duplicate definition: File[/etc/hadoop/conf/dfs.exclude] is already defined in file /var/lib/ambari-agent/puppet/modules/hdp-hadoop/manifests/init.pp at line 199; cannot redefine at /var/lib/ambari-agent/puppet/modules/hdp-hadoop/manifests/hdfs/generate_exclude_file.pp:36 on node *******
{code}

Repro steps:
Add hdfs-exclude-file config type - e.g.
{code}
curl --user admin:admin -i -X POST -d '{"type": "hdfs-exclude-file", "tag": "version1", "properties" : {"datanodes":""}}' http://localhost:8080/api/v1/clusters/c1/configurations
{code}

Then try to install DATANODE.
