Elastic search creates 5 shards in default in Elastic search 0.14.0

Hi,

I am indexing a doc with 1 shards and 0 replicas, but it creates 5
shards in default. Why its create like this ?.

Another question here is where is the replica's stored?

Hi,

if not set otherwise then 5 shards is the default used by Elastic Search.
Can you recreate your issue with simple curl example?

As for the replicas, Elastic Search makes sure that index shard and its
replica are not stored on the same node. This means that if you have an
index shard with one replica you need at least two (data) nodes to have them
allocated, if any replica can not be allocated due to insufficient number of
nodes available then you can learn it via Health API (status will be
yellow).

Thaks for your response...

I am using the curl command to create database is

$ curl -XPUT 'http://localhost:9200/testdb2/' -d '{index :
{number_of_shards
: 3, number_of_replicas : 0}}'

after getting database status it shows like below.

"settings":{"index.number_of_shards":"5","index.number_of_replica
s":"1"},

Hi,

Yea, this is a regression in 0.14, opened an issue:
Issues · elastic/elasticsearch · GitHub and
pushed a fix to master. This will probably require an 0.14.1 release to fix
it....
