Hi it depends of available resources of the nodes where you are planing to install all services. If your master nodes have enough resources you can have (HDFS,YARN,Zookeeper,HBase) on same nodes. In case of Kafka and NiFi I will recommend to install on separate machines. If you have 3 master nodes: 1. HDFS(Active),YARN(Active),HBase(Active),Zookeeper 2. HDFS(Standby),YARN(Standby),HBase(Standby),Zookeeper 3. Zookeeper ... View more

For Log Search default retention period is 7 days and for Ranger 90 days. I will recommend you to store it for default period of time + store all logs in hdfs. If you will delete old log files it wouldn't harm the system. ... View more

Hi, I will recommend you to install two HAproxy as a load balancer and configure keepalived (VRRP) between them. In this way you will have virtual ip to which you will refer ranger url. But keep in mind that ranger use relational database which also must have master-master replication if its mysql it can be Galera cluster. So you will have two HAproxy with virtual ip + two Ranger Admin instances + Galera Cluster for mysql. This configuration solves single point of fail in all steps. ... View more
