Subject [jira] [Commented] (YARN-5124) Modify AMRMClient to set the ExecutionType in the ResourceRequest
Date Mon, 06 Jun 2016 02:46:59 GMT

    [ https://issues.apache.org/jira/browse/YARN-5124?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=15316147#comment-15316147

Arun Suresh commented on YARN-5124:

[~kasha], thanks for the review..

I agree with 1-4 of your comments.. shall upload patch addressing them shortly..

w.r.t #5,
Given that {{ExecutionTypeRequest}} is a wrapper for the actual {{ExecutionType}}, the remoteRequestsTable
primary key should comprise the ExecutionType, not the ExecutionTypeRequest. I was thinking,
for the case where enforceExecutionType is false, we can possibly just match a returned Container
with any entry in the remoteRequestsTable (where Priority, Location and Capability match,
but the ExecutionType can be anything).
I intentionally left out the implementation, since currently, the only Distributed Scheduling
supports ExecutionTypes and it currently only supports enforceExecutionType = true. I would
be happy to put at doc with a TODO there (and maybe open a JIRA) to fix it once we have the
Scheduler fix that supports enforceExecutionType = false.
Thoughts ?
