@youngick kim I refer that link suggest, but I can not see any guide to solve my issue. Best answer saild : So for now... no load balancing for STS if the cluster is kerberized, otherwise haproxy, httpd +mod_jk or any other load balancer will probably do the work.

Currently I running only one Thrift server on my cluster. I see if I have many client connections, Spark run very slow. I find the solution for this and I see the doc: https://docs.hortonworks.com/HDPDocuments/HDP2/HDP-2.5.0/bk_spark-component-guide/content/install-spark-over-ambari.html It said: Deploying the Thrift server on multiple hosts increases scalability of the Thrift server; the number of hosts should take into consideration the cluster capacity allocated to Spark. So If I deploy more Thrift server on my cluster, Can I handle multiple concurrent client connections ? If not, how to I can handle this issue ?. And other question, Can I running two Spark apps with different configure on each? ... View more
