Hi ,

I am using \*spring-elasticsearch[https://github.com/dadoonet/spring-elasticsearch](https://github.com/dadoonet/spring-elasticsearch)  
\*I my configuration is

\_settings.json

{  
"index" : {  
"number\_of\_shards" : 3,  
"number\_of\_replicas" : 1  
}  
}

spring.xml

\<?xml version="1.0" encoding="UTF-8"?\>

\<elasticsearch:client id="esClient" esNodes="localhost:9300"  
properties="esproperties"  
autoscan="false" mappings="twitter/tweet" mergeSettings="true"mergeMapping="true"/\>

```
<util:properties id="esproperties" 

```

location="classpath:esclient-transport.properties"/\>

when i start the esClient 1st time it runs fine when i run the program  
again it throws exception as below this happens when i specify  
mergeSettings="true"

Exception in thread "main"  
org.springframework.beans.factory.BeanCreationException: Error creating  
bean with name 'esClient': Invocation of init method failed; nested  
exception is org.elasticsearch.ElasticSearchIllegalArgumentException: can't  
change the number of shards for an index

how to avoid this error . when should we use mergeSettings="true"

regards  
paul

Hmmm…

I think I understand. Factory is first trying to create a new index with your settings (3,1) than after a restart tries to update settings but number of shards is immutable.  
Could you open an issue in spring-elasticsearch project?

I would like to find a fix for it.

## Thanks
