It would help if you add along some description of what you have found or attempted, instead of just a broad question.
What load balancer are you choosing to use?
We have some sample HAProxy configs at https://www.cloudera.com/documentation/enterprise/latest/topics/impala_proxy.html#tut_proxy
for Impala that can be repurposed for other components.
Hue also offers its own pre-optimized Load Balancer as roles in Cloudera Manager that you can add and have it setup automatically: https://www.cloudera.com/documentation/enterprise/latest/topics/hue_perf_tuning.html
