Subject [jira] [Commented] (MAPREDUCE-2789) [MR:279] Update the scheduling info on CLI
Date Tue, 11 Oct 2011 00:54:29 GMT

    [ https://issues.apache.org/jira/browse/MAPREDUCE-2789?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=13124622#comment-13124622
] 

Arun C Murthy commented on MAPREDUCE-2789:
------------------------------------------

Thanks Eric.

Some minor nits:
# Need a null check for 'currentAttempt' in RMAppImpl.
# In RMAppAttemptImpl.getApplicationResourceUsageReport:
## You need to acquire the readLock.
## Reserved containers loop needs a +=, not =
# In ApplicationResourceUsageReport, please use Resource rather than int for all parameters/return-values.
We don't want to tie it to just memory.
# JobStatus
## Minor nit - please use 'Reserved' rather than 'Rsvd' for apis, we try to avoid these in
api names (maybe use expansion for variable names too?)
## I don't get why we need (get,set)ApplicationMasterInfo - we already have (get,set)TrackingUrl?
