             Summary: ContainerID in ResourceManager Log Has Slightly Different Format From AppAttemptID
                 Key: YARN-3017
                 URL: https://issues.apache.org/jira/browse/YARN-3017
             Project: Hadoop YARN
          Issue Type: Improvement
            Reporter: MUFEED USMAN
            Priority: Minor


Not sure if this should be filed as a bug or not.

In the ResourceManager log in the events surrounding the creation of a new
application attempt,

...
...
2014-11-14 17:45:37,258 INFO
org.apache.hadoop.yarn.server.resourcemanager.amlauncher.AMLauncher: Launching
masterappattempt_1412150883650_0001_000002
...
...

The application attempt has the ID format "_1412150883650_0001_000002".

Whereas the associated ContainerID goes by "_1412150883650_0001_02_".

2014-11-14 17:45:37,260 INFO
org.apache.hadoop.yarn.server.resourcemanager.amlauncher.AMLauncher: Setting up
container Container: [ContainerId: container_1412150883650_0001_02_000001,
NodeId: n67:55933, NodeHttpAddress: n67:8042, Resource: <memory:2048, vCores:1,
disks:0.0>, Priority: 0, Token: Token { kind: ContainerToken, service:
10.10.70.67:55933 }, ] for AM appattempt_1412150883650_0001_000002
...
...

Curious to know if this is kept like that for a reason. If not while using
filtering tools to, say, grep events surrounding a specific attempt by the
numeric ID part information may slip out during troubleshooting.
