Unassigned Shards Problem

I have five nodes : Two Master Nodes, One Balancer Node, One Workhorse
Node, and One Coordinator Node.

I am shipping events from logstash, redis, to elasticsearch.

At the moment, my cluster is RED. The shards are created but no index is
created. I used to get an index like logstash.2014-05-22, but not anymore.

I deleted all my data, Cluster health goes GREEN.

However, as soon as data is sent from logstash -> redis -> elasticsearch,
my cluster health goes RED. I end up with unassigned shards. In my
/var/log/elasticsearch/logstash.log on my master, I see this in the log:

[2014-05-22 12:03:20,599][INFO ][cluster.metadata ] [Bora]
[logstash-2014.05.22] creating index, cause [auto(bulk api)], shards
[5]/[1], mappings [default]

On my master, this is the configuration:

cluster:
name: logstash
routing:
allocation:
awareness:
attributes: rack
node:
data: true
master: true

curl -XGET 'http://localhost:9200/_cluster/health?pretty=true'
{
"cluster_name" : "logstash",
"status" : "red",
"timed_out" : false,
"number_of_nodes" : 5,
"number_of_data_nodes" : 3,
"active_primary_shards" : 0,
"active_shards" : 0,
"relocating_shards" : 0,
"initializing_shards" : 0,
"unassigned_shards" : 10
}

Is there an incorrect setting? I also installed ElasticHQ. It tells me the
same information.

It does create an index, it says so in the log - [logstash-2014.05.22]
creating index - it's jut not assigning things.

You've set routing.allocation.awareness.attribute, but have you set the
node value, ie node.rack?

Thanks for your reply. I set the node.rack to rack_one on all the nodes as
a test. In ElasticHQ, on the right it shows no indices. It is empty. In my
master, I see that the nodes are identifying with rack_one (all of them).

Any other clues?

Thanks

Brian

Went back and read the page again. So I made one master, workhorse, and balancer with rackid of rack_two for testing. One master shows rackid of rack_one. All nodes were restarted. The shards are still unassigned. Also,the indices in ElasticHQ are empty.

I removed all the extra allocation stuff. When I did that, the shards were
all propogated. Health is green again.
