 Summary: yarn.admin.acl is futile
 Key: YARN-9445
 URL: https://issues.apache.org/jira/browse/YARN-9445
 Project: Hadoop YARN
  Issue Type: Bug
  Components: security
Affects Versions: 2.6.0
Reporter: Peter Simon


* Define a queue with restrictive administerApps settings (e.g. yarn)
 * Set yarn.admin.acl to "*".
 * Try to submit an application with user yarn, it is denied.

This way my expected behaviour would be that while everyone is admin, I can 
submit to whatever pool.

[jira] [Created] (YARN-7686) Yarn containers failover if datanode/nodemanager fails

2017-12-28 Thread Peter Simon (JIRA)

 Summary: Yarn containers failover if datanode/nodemanager fails
 Key: YARN-7686
 URL: https://issues.apache.org/jira/browse/YARN-7686
 Project: Hadoop YARN
  Issue Type: New Feature
  Components: resourcemanager
Affects Versions: 2.6.0
Reporter: Peter Simon


While running an application on Yarn, one of the datanodes/nodemanagers went 
offline due to power issues. The first application attempt was failed due to 
lost containers. When the second attempt started, there were no heartbeat 
interval happened to the Namenode, and the second attempt still got the 
datanode/nodemanager as possible worker node for the containers. While the host 
was unreachable, therefore the container attempts were failed, led to the 
second application attempt also failed, caused the application failure.
There could be a failover process for container attempts, so if on one node new 
container can't be brought up, the ResourceManager should try to allocate the 
new container on a different node.
