Subject [jira] [Updated] (MAPREDUCE-2137) Mapping between Gridmix jobs and the corresponding original MR jobs is needed
Date Thu, 26 May 2011 06:29:47 GMT

     [ https://issues.apache.org/jira/browse/MAPREDUCE-2137?page=com.atlassian.jira.plugin.system.issuetabpanels:all-tabpanel

Ravi Gummadi updated MAPREDUCE-2137:

    Attachment: 2137.v2.1.patch

Attaching new patch. With this patch,

(1) The gridmix simulated job name is of the format GRIDMIX<6-digit-sequence-number>

(2) The configuration properties gridmix.job.original-job-id and gridmix.job.original-job-name
in the configuration of simulated job are exposed/documented to gridmix user. These config
properties are to be used for mapping a simulated job to its corresponding original job from
trace file.

> Consider a trace file "trace1" obtained by running Rumen on a set of MR jobs' history
logs. When gridmix runs simulated jobs from "trace1", it may skip some of the jobs from the
trace file for some reason like out-of-order-jobs. Now use Rumen to generate trace2 from the
history logs of gridmix's simulated jobs.
> Now, to compare and analyze the gridmix's simulated jobs with original MR jobs, we need
a mapping between them.
