Hive LLAP Daemons not consuming Cluster VCPU allocation. 80-100 cores available for LLAP daemon, but only using 16.
I am testing Hive LLAP on Azure using 2 D14_v2 head nodes, 16 D14_V2 Worker Nodes, and 3 A series Zookeeper nodes. (D14_V2 = 112GB Ram/12vcpu) The 15 nodes of the 16 node Cluster is dedicated to LLAP.
The Distribution is HDP 126.96.36.199-14
Currently the cluster has a total of 1.56TB of Ram Available and 128vcpu. The LLAP Daemons are allocated the proper amount of memory, but the LLAP Daemons only uses 16vcpus total ( 1 vcpu per daemon + 1 vcpu for slider).
My relevant hive configs are as follows:
hive.llap.daemon.num.executors = 10 (10 of the 12 available vcpu per node)
Yarn Max Vcores per container - 8
I have been load testing the cluster but unable to get any more vcpus engaged in the process. Any thoughts or insights would be greatly appreciated.
