Query Perfomance is Slow or Stuck in Hive LLAP

5 Node cluster(HDP 2.7 and hive 1.2) with hive llap

When I'm running the Queries from Hivellap facing very slow or Stuck.

How to debug the query performance from cluster side.

LLAP Daemon/AM Memory configuration:

LLAP Daemon Container Max Headroom = 12288 MB

LLAP Daemon Heap Size (MB) = 55300 MB

In-Memory Cache per Daemon = 15360 MB

Memory per Daemon = 82944 MB (Max Headroom + Heap Size + Cache)

Slider AM container size = 27648 MB

TEZ Configurations: hive.tez.container.size 4096
