I've been running ElasticSearch 0.6.0 for a little while now, and awaiting the new cloud plugin in 0.7.1.
I'm now trying to work out how to migrate my cluster over to the cloud module because I've come across a little trouble. Currently my nodes are running 0.6.0, using jgroups for discovery, with gateway, and I want to switch to cloud for both, but I'd really rather not shut down my cluster to do this, but to be able to go through a process something like this:
- join a node which is configured to use the cloud for its gateway to the cluster,
- remove one of the existing nodes, so the shards moved are moved to the new machine,
- shut down that new machine and reconfigure it to use the cloud for discovery
- start up a second machine configured to use the cloud for discovery and as a gateway
- when I have verified the migration, shut down the old 0.6.0 machine
I'm struggling, however to execute the first step, because I can't seem to get the new machine to use jgroups to connect to the cluster.
I was also wondering if there might be a better way. This was all I could come up with on a Monday morning
I'd appreciate any thoughts that people might have.
