Subject [jira] [Commented] (YARN-2859) ApplicationHistoryServer binds to default port 8188 in MiniYARNCluster

-----------------------------------------

Hi [~sjlee0],
Ok to reword it , suppose we enable {{yarn.resourcemanager.system-metrics-publisher.enabled}}
in 2.7.2 and run TestDistributedShell then we face the same problem(SMP will fail to connect
to timeline server) with the miniyarn cluster. Hence this fix is not complete fix but none
of the test cases fail. So if *MINI YARN cluster is required to be used with system-metrics-publisher
enabled* then its required to fix and its faster to fix in my way.  If MINIYARN cluster doesn't
require *system-metrics-publisher enabled* then for ATS v2 we will have to change it as part
of YARN-4350.

> In mini cluster, a random port should be used. 
> Also, the config is not updated to the host that the process got bound to.
