Hi Nik, I found the that I am not able to do decommissioning over multiple nodes. I can do decommissioning over a single node.
These cmds below work perfectly for my ES cluster: "cluster.routing.allocation.exclude._name": "node-1" "cluster.routing.allocation.exclude._name": "node-2" "cluster.routing.allocation.exclude._ip": "ip1" "cluster.routing.allocation.exclude._ip": "ip2" But none of these cmds below has effect for my ES cluster: "cluster.routing.allocation.exclude._name": "node-1,node-2" "cluster.routing.allocation.exclude._name": ["node-1", "node-2"] "cluster.routing.allocation.exclude._ip": "ip1,ip2" "cluster.routing.allocation.exclude._ip": "ip1, ip2" I also notice that extra spaces for "_name" or "_ip" field cause the cmd to fail (no effect). For example, none of these cmds below works. "cluster.routing.allocation.exclude._ip": " ip1 " "cluster.routing.allocation.exclude._name": "node-1 " I am running this version of ES on Ubuntu 14.04: > elasticsearch -v Version: 1.4.0, Build: bc94bd8/2014-11-05T14:26:12Z, JVM: 1.8.0_25 I checked release notes of ES 1.4.1 and 1.4.2, and I didn't find some bug fixing notes for this "decommissioning over multiple nodes" function. Is this a bug? Or, I omit something important?
