Hi,
I have a question regarding balance settings of Elasticsearch. I have 10
nodes and each index has 10 shards (5 primary, 5 replica). I want for
all nodes to have only 1 shard of an index. The documents explains some
settings here [elasticsearch@googlegroups.com](mailto:elasticsearch@googlegroups.com) to do this, but I am not
sure what values to use. Is it a good idea to set 1.0 first three
settings? Is there any possible problems if I change these settings?
Best,
Umutcan

If you start 10 nodes and have 10 shards to allocate, elasticsearch will most likely do what you are expecting: 1 shard per node.
So you don’t really need to define any setting but just use elasticsearch defaults which are good most of the time.

You are right. Elasticsearch distribute shards to 10 nodes most of the
time. But there are exceptions and I want to guarantee it that every
time shards will be distributed even or at least decrease frequency of
these exceptions.
