Evans Ye commented on BIGTOP-1174:
----------------------------------
[~mackrorysd]
To clarify my original thought when providing the patch, the code snippet
{code}
Hadoop::Namenode<||> -> Hadoop::Datanode<||> -> Exec<| title == "init hdfs" |>
{code}
chain
[collectors|http://docs.puppetlabs.com/puppet/2.7/reference/lang_collectors.html]
in the following [executing
order|http://docs.puppetlabs.com/puppet/2.7/reference/lang_relationships.html#chaining-arrows]:
first, run all the resources found in Hadoop::Namenode namespace
second, run all the resources found in Hadoop::Datanode namespace
thrid, run the Exec resource which has title equal to "init hdfs"
Just In case if you would like to leave any comments on the patch:)
> missing dependency setting on init-hdfs.sh in puppet recipes

> Key: BIGTOP-1174
> URL: https://issues.apache.org/jira/browse/BIGTOP-1174
> Project: Bigtop
> Issue Type: Bug
> Components: Deployment
> Affects Versions: 0.7.0
> Reporter: Evans Ye
> Assignee: Sean Mackrory
> Fix For: 0.8.0
>
> Attachments: BIGTOP-1174.1.patch
>
>
> There's no dependency setting to explicitly define {{init-hdfs.sh}} to be
> executed after hdfs get ready, so when running the puppet recipes to deploy a
> hadoop environment, the {{init-hdfs.sh}} script failed to setup folders and
> permissions on hdfs since it will be executed before namenode and datanode
> has been started.
> Sample output:
> {code}
> notice:
> /Stage[main]/Hadoop_worker_node/Hadoop::Datanode[datanode]/File[/data/1/hdfs]/mode:
> mode changed '0700' to '0755'
