Hello, there are a total of 16 nodes in the cluster, including 13 data nodes and 3 master nodes.
Master nodes have 64 gb ram. But jvm heap is set to 16gb.
Data nodes have 64 GB ram. But jvm heap is set to 30gb.
Does the jvm heap value of all servers need to be 32 gb regardless of master node or data node? Also would it be a problem if I set the jvm heap to 32gb?
I'm getting an outofmemory error when transferring data with Logstash. Could this have something to do with the situation?
