Is it possible to create indexes on one node of a cluster and copy it to another

Elastic Stack Elasticsearch
1

Hello,
I'm wondering if it's possible to create an elasticsearch index on one node
in the cluster and then when it is complete copy it to another node....(and
ultimately delete from the original). In rare cases it is necessary to
rebuild indexes into smaller indexes. I'm thinking that if we had a
"souped" up server with maybe more memory and/or CPU's we could rebuild the
index on this server without impacting other servers. When the index
re-build is complete we could just tar it up (or copy) it to a different
server...(and maybe just update metadata appropriately).

Anyone know if this is possible?

Thanks

Yes you can. In fact the easiest way would be:

  1. start a new node with a different cluster name (so it forms its own
    cluster)
  2. index into that node
  3. shut it down
  4. change the cluster name to the main cluster name and restart
    -> it joins the main cluster, which imports the new index
    and allocates replica shards within the existing nodes
  5. Once cluster is green, shut down the extra node
    -> the replica shards are promoted to primaries, and it
    allocates new replicas on other machines within the cluster
