Subject [jira] [Commented] (MAPREDUCE-6838) [ATSv2 Security] Add timeline delegation token received in allocate response to UGI
Date Fri, 18 Aug 2017 06:52:00 GMT

    [ https://issues.apache.org/jira/browse/MAPREDUCE-6838?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=16131811#comment-16131811

Rohith Sharma K S commented on MAPREDUCE-6838:

thanks [~varun_saxena] for the patch. It seems patch do not apply, required to rebase.
# Why are changing hadoop-common code to ignore ignoreUseIpConfig? Is this because to add
test case? Does test is failing? 
# I just noticed that TimelineDelegationTokenIdentifier#Renewer has methods renew/cancel.
These creates V1 client. Does it going to be a problem?
# I think it is better to update token on each heart beat rather then comparing each time.
It avoids proto compare.
# This appears mixing collectorManager i.e NMCollectorService authentication and MR side.
Is both required here or can we raise new JIRA? Was it conflicting with MR publisher ? One
thing I observe is TimelineClient is published using login user which is doAS. I think we
should publish is as owner of application otherwise we end up in writing data into sub app
application table as well.
