Subject [jira] [Commented] (MAPREDUCE-5311) Replace SLOTS_MILLIS counters with MEM_MILLIS
Date Thu, 15 Aug 2013 02:22:48 GMT

    [ https://issues.apache.org/jira/browse/MAPREDUCE-5311?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=13740594#comment-13740594
] 

Vinod Kumar Vavilapalli commented on MAPREDUCE-5311:
----------------------------------------------------

bq. Is there an issue with MR code using the existing (and possible in future deprecated)
min resource YARN configuration for its internal calculations?
Lets just do this and like I argued on YARN-1004, let's keep the min around as a RM property
and use it for the SLOTS_MILLIS calculation. For Fifo and CS, things will just work. For FairScheduler,
the new config hack is same as forcing operators to set the existing RM property.

BTW, please edit back the title to just indicate the problem.

> Per discussion in MAPREDUCE-5310 and comments in the code we should remove all the related
logic and just leave the counter constant for backwards compatibility and deprecate the counter
constants.
