Subject [jira] [Commented] (YARN-2740) ResourceManager side should properly handle node label modifications when distributed node label configuration enabled
Date Tue, 21 Apr 2015 23:05:59 GMT

    [ https://issues.apache.org/jira/browse/YARN-2740?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=14505972#comment-14505972
] 

Naganarasimha G R commented on YARN-2740:
-----------------------------------------

bq. No, we've decided to support remove node labels while distributed config enabled, I think
it's better to add test to make sure it works in distributed mode. Since "remove label = remove
label in the cluster + remove label in nodes, it's a defensive test case to avoid future code
changes break this.
ok got it, had misread your comment earlier
bq. We can continue to support both of the 2, just extra common part should be enough.
ok, Will extract the common part to a method .

> According to YARN-2495, when distributed node label configuration is enabled:
> - RMAdmin / REST API should reject change labels on node operations.
> - CommonNodeLabelsManager shouldn't persist labels on nodes when NM do heartbeat.
