Subject [jira] [Commented] (MAPREDUCE-3451) Port Fair Scheduler to MR2
Date Sun, 15 Apr 2012 06:57:32 GMT

    [ https://issues.apache.org/jira/browse/MAPREDUCE-3451?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=13254273#comment-13254273
] 

Aaron T. Myers commented on MAPREDUCE-3451:
-------------------------------------------

bq. For the documentation pointer (hadoop-mapreduce-project/hadoop-yarn/hadoop-yarn-site/src/site/apt/)
- I'm unfamiliar with the markup being used in these documents (it looks like the Velocity
engine maybe?). 

Take a look at this page for info on the markup: http://maven.apache.org/doxia/references/apt-format.html

bq. Is there any way to render these files locally as I'm writing some preliminary docs for
the FS?

>From the repo root, `cd hadoop-mapreduce-project/hadoop-yarn/hadoop-yarn-site' and run
`mvn site'. You can then look at the rendered page by browsing to "file:///<path to repo>/hadoop-mapreduce-project/hadoop-yarn/hadoop-yarn-site/target/site/<file
name>.html"

> The Fair Scheduler is in widespread use today in MR1 clusters, but not yet ported to
MR2. This is to track the porting of the Fair Scheduler to MR2 and will be updated to include
design considerations and progress.
