-----------------------------------
Summary: Fix the currentAppAttemptId error in AHS when an
application is running
Key: YARN-7820
URL: https://issues.apache.org/jira/browse/YARN-7820
Project: Hadoop YARN
Issue Type: Bug
Components: timelineserver
Reporter: Jinjiang Ling
Assignee: Jinjiang Ling
Attachments: image-2018-01-26-14-35-09-796.png
When I using the REST API of the AHS to get a running app's latest attempt id,
it always returns a invalid id like
*appattempt_1516873125047_0013_{color:#FF0000}-000001{color}*.
But when the app is finished, the RM will push a finished event which contains
the latest attempt id to TimelineServer, so the id will transitive to a correct
one in the end of the application.
I think as the app is running, this value should be a correct one, so I add the
latest attempt id in the other info of the app's entity when the app trans to
RUNNING state. Then the AHS will use this value to set the currentAppAttemptId.
