Chengxiang Li commented on SPARK-5439:
--------------------------------------
I think the gap here is that, when launch a Hive CLI with Spark deployed on
YARN, from the YARN webUI page, the user want to know which YARN application is
allocated for his hive session, then he can check the status of his application
through ApplicationMaster tracking UI.
[~vanzin], is the YARN application ID same as SparkContext applicationID? From
my experience, seems not. The YARN web UI shows that the YARN application ID
schema is like:application_\*, and SparkContext applicationID is set at
SchedulerBackend#26 with schema spark-application-*.
> Expose yarn app id for yarn mode
