Naganarasimha G R updated YARN-2729:
------------------------------------
Attachment: YARN-2729.20151310-1.patch
Thanks for the review [~rohithsharma],
bq. Does ScriptBasedNodeLabelsProvider is periodically runs similar to
ConfigurationNodeLabelsProvider?
Yes as it extends AbstractNodeLabelsProvider it supports periodic execution.
bq. Is there anywher documented how the script output should be?
yes its documented in *yarn-default.xml* and javadocs for the class
*ScriptBasedNodeLabelsProvider.java*. Do you have any other place in mind where
it can be updated?
bq. About the test TestNodeStatusUpdaterForLabels failing randomly.May be some
race condition is exist.
Yes this is issue has been already raised as YARN-4169, but nutting to do in
specific to this jira and was not actually reproducible in my local setup.
bq. When I run tests locally at package level i.e
org.apache.hadoop.yarn.server.nodemanager.nodelabels, all the tests cases in
TestScriptBasedNodeLabelsProvider are failing with below error
Not facing this issue, will sync offline with you on this.
Other issues have been handled in the patch along with one more minor issue
which was got during testing, In ResourceTrackerService we are checking for
distributed or delegated-centralized without checking for node labels enabled
which caused unnecessary logs on RM side.
