Tassapol Athiapinya created YARN-1081:
-----------------------------------------
Summary: Minor improvement to output header for $ yarn node -list
Key: YARN-1081
URL: https://issues.apache.org/jira/browse/YARN-1081
Project: Hadoop YARN
Issue Type: Improvement
Components: client
Reporter: Tassapol Athiapinya
Fix For: 2.1.0-beta
Output of $ yarn node -list shows number of running containers at each node. I
found a case when new user of YARN thinks that this is container ID, use it
later in other YARN commands and find an error due to misunderstanding.
