Subject [jira] [Updated] (YARN-919) Setting default heap sizes in yarn env
Date Fri, 19 Jul 2013 01:25:46 GMT

     [ https://issues.apache.org/jira/browse/YARN-919?page=com.atlassian.jira.plugin.system.issuetabpanels:all-tabpanel

Hitesh Shah updated YARN-919:

    Attachment: YARN.919.4.patch

[~mayank_bansal] Thanks for addressing the review comments. Looking at bin/yarn in a bit more
detail, I noticed a couple of other gotchas that can affect users when setting heapsize. In
that aspect, I have attached a patch with a bit more verbose documentation. 

Let me know what you think.

> Right now there are no defaults in yarn env scripts for resource manager nad node manager
and if user wants to override that, then user has to go to documentation and find the variables
and change the script.
> There is no straight forward way to change it in script. Just updating the variables
with defaults.
