-----------------------------------------
Hi [~wangda],
Thanks for discussing and summarizing this, few points to discuss:
# YARN-2923 (configuration based NodeLabelProviderService), what is the scope
of this jira as its again one more classification under {{distributed}} ?
whether is it req?
# Apart from the Vinod's suggestion, i would like to add one more change : In
some jiras we were discussing to have fail fast approach i.e. in our case if we
configure script based distributed configurations and the script file doesn't
exist, rights not sufficient etc.. then NM should fail to start.
# yarn-2980 is mostly just moving NodeHealthScriptRunner to HadoopCommon and
the code in it differs a lot than what we req, if you remember earlier i had
refactored that code and make it reusable for our scenario but you had
suggested not to touch the existing NodeHealthScriptRunner and to make
ScriptBasedNodeLabelsProvider similar NodeHealthScript serving the needs of
Node labels.
# Earlier target version was mentioned as 2.6, do we modify it to 2.7 or 2.8?
> Allow admin specify labels from each NM (Distributed configuration)

> Target of this JIRA is to allow admin specify labels in each NM, this covers
> - User can set labels in each NM (by setting yarn-site.xml (YARN-2923) or
> using script suggested by [~aw] (YARN-2729) )
> - NM will send labels to RM via ResourceTracker API
> - RM will set labels in NodeLabelManager when NM register/update labels
