Thomas Graves created YARN-1942:
-----------------------------------
Summary: ConverterUtils should not be Private
Key: YARN-1942
URL: https://issues.apache.org/jira/browse/YARN-1942
Project: Hadoop YARN
Issue Type: Bug
Components: api
Affects Versions: 2.4.0
Reporter: Thomas Graves
ConverterUtils has a bunch of functions that are useful to application masters.
It should either be made public or we make some of the utilities in it public
or we provide other external apis for application masters to use. Note that
distributedshell and MR are both using these interfaces.
For instance the main use case I see right now is for getting the application
attempt id within the appmaster:
String containerIdStr =
System.getenv(Environment.CONTAINER_ID.name());
ConverterUtils.toContainerId
ContainerId containerId = ConverterUtils.toContainerId(containerIdStr);
ApplicationAttemptId applicationAttemptId =
containerId.getApplicationAttemptId();
I don't see any other way for the application master to get this information.
If there is please let me know.
