Hi,

I've migrated from elasticsearh **2.3.4** to **5.1.2** , and tried hard to get my cluster discovered

I have a cluster of three data nodes, and one client node in front of them making requests.

But since the update, I have all my shards UNASSIGNED (412 shards)/

I tried to reallocate them following the new guideline, but it's not working , I don't have any shard initialized.

The command I run from the client node is :

```auto
for shard in $(curl -XGET http://10.3.16.91:9200/_cat/shards | grep logstash-2016.12.09 | grep UNASSIGNED | awk '{print $2}'); do
    curl -XPOST 'http://10.3.16.91:9200/_cluster/reroute' -d '{
        "commands" : [ {
              "allocate_stale_primary" : {
                  "index" : "logstash-2016.12.09", 
                  "shard" : '"$shard"', 
                  "node" : "es-cluster.i-0db3ba0f4287fb527", 
                  "accept_data_loss" : truePreformatted text
              }
            }
        ]
    }'
    sleep 3
done 

And this is the kind of message I'm having in the screeenshot

Can you hep make my cluster up and running?
```
