Kylin Cluster Mode. I am using Kylin on EMR. Is a restart of kylin required on all job and query servers when new node is added. Then there will be downtime. How do we achieve High Availibility.
from the guide: " Configure the Kylin node list kylin.server.cluster-servers, including all nodes (the current node is also included). When the event changes, the node receiving the change needs to notify all other nodes (the current node is also included). " So if I have 2 job servers and 2 query servers: then kylin.server.cluster-servers=jobnode1:7070,jobnode2:7070,querynode1:7070,querynode2:7070 If let's say query node 2 on EMR fails. And I add a new node with new EMR which will have a new IP. Then for the new node: kylin.server.cluster-servers=jobnode1:7070,jobnode2:7070,querynode1:7070,querynode3:7070 And then looks like I have to change the string on all the nodes to: kylin.server.cluster-servers=jobnode1:7070,jobnode2:7070,querynode1:7070,querynode3:7070 And then restart kylin on all nodes. This will incur downtime. Can you please help me understand how High Availability can be achieved then. Thanks in advance! -- Sent from: http://apache-kylin.74782.x6.nabble.com/
