Young Chen commented on YARN-7929: ---------------------------------- Hi [~yangjiandan], I just committed a patch to enable generic AM simulators for synthetic load generation, and after giving this patch a quick read through, I think you'll run into some merging issues. Let me know if you have any questions about the code I committed, I'll be happy to help. On a side note, I was actually looking to enable Opportunistic containers in SLS, so I'm very much looking forward to this patch! Quick question: What's the purpose of adding the "water level" to the NMSimulator? {code:java} if (waterLevel > 0 && waterLevel <=1) { int pMemUsed = (int) (node.getTotalCapability().getMemorySize() * waterLevel); float cpuUsed = node.getTotalCapability().getVirtualCores() * waterLevel; ResourceUtilization resourceUtilization = ResourceUtilization.newInstance(pMemUsed, pMemUsed, cpuUsed); ns.setContainersUtilization(resourceUtilization); ns.setNodeUtilization(resourceUtilization); } {code} > SLS supports setting container execution > ---------------------------------------- > > Key: YARN-7929 > URL: https://issues.apache.org/jira/browse/YARN-7929 > Project: Hadoop YARN > Issue Type: Sub-task > Components: scheduler-load-simulator > Reporter: Jiandan Yang > Assignee: Jiandan Yang > Priority: Major > Attachments: YARN-7929.001.patch > > > SLS currently support three tracetype, SYNTH, SLS and RUMEN, but trace file > can not set execution type of container. > This jira will introduce execution type in SLS to help better simulation. > This will help the perf testing with regarding to the Opportunistic > Containers. > RUMEN has default execution type GUARANTEED > SYNTH set execution type by field map_execution_type and > reduce_execution_type > SLS set execution type by field container.execution_type > For compatibility set GUARANTEED as default value when not setting above > fields in trace file -- This message was sent by Atlassian JIRA (v7.6.3#76005) --------------------------------------------------------------------- To unsubscribe, e-mail: yarn-issues-unsubscr...@hadoop.apache.org For additional commands, e-mail: yarn-issues-h...@hadoop.apache.org
