CatAliases API

[DivyaMalini]

Hi
I am using CatAliases API to get the list of all aliases .
My request is something like
ICatAliasesRequest catAliasesRequest = new CatAliasesRequest();
return m_elasticClient.CatAliases(catAliasesRequest);

and i am trying to read every record received from response(IEnumerable). I am observing that the records returned only have alias and index information and returns null for Search and Index routing .

Could anyone please confirm if this is a known issue or point me if i am doing something wrong ?

Thanks in advance !!

Hi @DivyaMalini,

Did you set routing value during alias creation? Have a look into documentation.

This is how you can do this with the NEST:

• Object initializer

var putAliasResponse = client.PutAlias(new PutAliasRequest("name")
{
    Routing = "routing"
});

• Fluent

var putAliasResponse = client.PutAlias(a => a
    .Index(indexName)
    .Name("name")
    .Routing("routing"));

Hope it helps.

Hi @robertlyson ,

Yes i had set the routing value during alias creation. Even when i directly run the command through sense plugin (GET _cat/aliases), the results displayed has SearchRouting values set. It is when I used the API in my c# code , i found the results whose routing values are null .

@DivyaMalini may you share more information about your alias?

@robertlyson ,

My PutAlias call is defined like this

public IPutAliasResponse PutAlias(string indexName, string aliasName)
{
var request = new PutAliasRequest(aliasName)
{
Index = new IndexNameMarker()
{
Name = indexName
},
Routing = Gid.NewGuid()
};
return elasticClient.PutAlias(request);
}

The _cat/Aliases call through sense plugin gives aliasName, indexName, Filter, Search and Index routing.

But when executed via code
public ICatResponse CatAliases(ICatAliasesRequest request)
{
CatAliasesRequest req = new CatAliasesRequest();
client.CatAliases(req);
}

in the catAliasesRecord obtained all the aliases routing(index and search) are returned null

FYI , i use Nest 1.6.0

@DivyaMalini looks like a bug, so I've created #1593 to address this issue.
