Hive LLAP throws Unable to process container ports mapping

Question

Im trying to get Hive LLAP to run on my server.

My setup so far is: Hadoop 3.31, tez 0.9.2, hive 3.1.2, zookeper 3.7.0 all from tar files.

Hive on Tez is working. Selects return the expected results.

Now i wanted to get LLAP running so i setup the config files and generated the scripts with:

hive --service llap --name llap0 --instances 2 --size 6g --loglevel DEBUG --cache 2g --executors 2

The yarn application is successfully started but in the application logs it says:

2021-11-29 13:21:46,390 [pool-5-thread-2] WARN  instance.ComponentInstance - Unable to process container ports mapping: {}

So the services is starting containers but i can not connect to it.

Is there any option i am missing or where do i setup the port mapping?
