Bikas Saha created YARN-959:
-------------------------------
Summary: Add ApplicationAttemptId into container environment
Key: YARN-959
URL: https://issues.apache.org/jira/browse/YARN-959
Project: Hadoop YARN
Issue Type: Improvement
Affects Versions: 2.1.0-beta
Reporter: Bikas Saha
Currently, AM's and containers have to read the container id and then derive
the application attempt id from it. While its convenient for YARN to tightly
couple container id with application attempt id, it is something that should
not be exposed to users. Its easy to let users know about their application
attempt id via env instead of requiring them to pull it out of the container id.
