You are right. It should be ok if the new node joined before I remove old one, but the new master joined cluster after I removed the old one.

I will change my cluster configuration. I think it is better to make all nodes both data and master.

But, my question still remains. Is there a way to recover those indices from files?

If your new master capable node joined the cluster then it would have received the cluster state metadata, and (presuming things are all ok) when you remove the old master then it should be promoted and take over without problems.

I don't really know much about the AWS plugin though, but a standard cluster works in that manner.

    I am using 1.4.0 version. There is nothing in the logs.

    I started new master after I shut down the old one. I thought new
    master could detect indices, but I guess master node stores some
    meta data related to indices and these data is gone with the old
    master node. New master created all the indices from scratch.

    I use timestamp in the index names, so indices before yesterday is
    still remains in the data nodes. I want to load these indices.

        Yes, it did and both are set to true.

        But, it did not join the cluster until I shut down the old
        master.

        Is it set to master: true and data:true?

            Hi,

            I have a cluster with 1 master and 3 data nodes. I
            needed to change master node. So, I created a new master
            node and shutdown the old one.  Both are EC2 instances.
            After doing this new master did not find old indices.
            All the files belong to old indices still remains inside
            the data nodes.

            Is there a way to make new master node find those files
            and use old indices?

            Thanks,
            Umutcan
