Subject [jira] [Commented] (YARN-2497) Changes for fair scheduler to support allocate resource respect labels
Date Wed, 30 Aug 2017 10:10:02 GMT

    [ https://issues.apache.org/jira/browse/YARN-2497?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=16147013#comment-16147013

YunFan Zhou commented on YARN-2497:

Thanks for working on this, [~templedf]. some nits:
# We should guarantee that a queue with non-label cannot access a node with a label, which
is very important to us.
# Do we need to support a node with multiple labels? I found that CS has chosen not to support
this feature.
# We need to support *relaxed (non-exclusive) partitions*, which is a strong demand for me.
If no one is willing to invest time, I will take the time to complete this requirement.
# The node label failover mechanism needs to be considered.
# A queue should only access one label, and if we support a queue can access multiple labels,
the semantics may need to be explicitly defined. The other thing is that we need to have a
default label if the resource request does not specify a default label.
