Description

Hadoop 2.6 env - RM HA enabled

Steps:
1) Create an application using Slider
2) Go to RM web UI. Click on ApplicationMaster link of the running application. It says -

This is standby RM. Redirecting to the current active RM: <app_uri>

This happens in Slider 0.60 even though the following YARN bugs are fixed in Hadoop 2.6 and needs investigation -

YARN-1525
YARN-1811
YARN-2605

Issue Links

• depends upon: YARN-3526 ApplicationMaster tracking URL is incorrectly redirected on a QJM cluster
• is blocked by: YARN-2605 [RM HA] Rest api endpoints doing redirect incorrectly
