[jira] [Updated] (MAPREDUCE-2107) Emulate Memory Usage of Tasks in GridMix3

     [ https://issues.apache.org/jira/browse/MAPREDUCE-2107?page=com.atlassian.jira.plugin.system.issuetabpanels:all-tabpanel ]

Amar Kamat updated MAPREDUCE-2107:
----------------------------------

    Attachment: gridmix-memory-emulation-v1.5.patch

Attaching a patch the adds total-heap-usage emulation to Gridmix. The goal is to do a very basic heap usage emulation and using this tool to exert some sort of memory load on the simulated task's JVM. This patch also sets the simulated task's heap options extracted from the original job obtained via Rumen. 

test-patch and gridmix junit tests passed.

> MAPREDUCE-220 makes CPU/Memory usage of Tasks available in JobHistory files. Use this
> to emulate the memory usage of Tasks (of course, once MAPREDUCE-2104 is done).
