Subject [Hadoop Wiki] Update of "WritingYarnApps" by ChrisRiccomini
Date Wed, 21 Sep 2011 03:50:59 GMT
Dear Wiki user,

You have subscribed to a wiki page or wiki category on "Hadoop Wiki" for change notification.

The "WritingYarnApps" page has been changed by ChrisRiccomini:
http://wiki.apache.org/hadoop/WritingYarnApps?action=diff&rev1=4&rev2=5

    * ClientRMProtocol -> Protocol for job-client (launching program from gateway) to talk
to RM to launch a new application i.e. application master itself
    * AMRMProtocol -> Protocol for AM to use to register/stop itself and get resources
from the Scheduler
  
+ === FAQ ===
+ 
+ '''How can I distribute my application's jars distributed to all of the nodes in the YARN
cluster that need it?'''
+ 
+ '''Why does my application's client have to send the app ID/attempt ID/cluster timestamp
to my application master?'''
+ 
+ This is actually going to be improved. It will likely become environment variables, or substituted
variables (like the fail count). For more details, track this ticket: https://issues.apache.org/jira/browse/MAPREDUCE-3055
