Can we also select dedicated hosts/nodes which can be used by Hive's LLAP?

Hi Everyone,

We are working on configuring LLAP where we need to use only 5 dedicated servers. We found that we can choose the number on nodes used by LLAP but can we also select the hosts/nodes for llap.

Any help on this?

Hi @Shyam Shaw. You can't specify nodes in the LLAP configuration but can leverage node labels. https://docs.hortonworks.com/HDPDocuments/HDP2/HDP-2.6.1/bk_yarn-resource-management/content/ch_node_labels.html.

You'll want to go into the LLAP YARN queue and enable node labels to dedicate nodes to LLAP.
