Hi, For some reason I can't get the java client working on EC2. My elasticsearch cluster and the cluster running my java application are in two different security groups ('elasticsearchrealtime' and 'storm'), in the same aws region. I am using elasticsearch version 0.90.2 and using the cloud aws plugin version 1.12.0. (in my es cluster and in my java application) I tried lot of combinations for the properties, and none of them worked. I always get the following warning : [Elastic Search Realtime Client] waited for 30s and no initial state was set by the discovery And after that, each time the java application is trying to interact with the client the following exception is thrown : org.elasticsearch.discovery.MasterNotDiscoveredException: waited for [30s] at org.elasticsearch.action.support.master.TransportMasterNodeOperationAction$3.onTimeout(TransportMasterNodeOperationAction.java:169) at org.elasticsearch.cluster.service.InternalClusterService$NotifyTimeout.run(InternalClusterService.java:377) at java.util.concurrent.ThreadPoolExecutor.runWorker(ThreadPoolExecutor.java:1110) at java.util.concurrent.ThreadPoolExecutor$Worker.run(ThreadPoolExecutor.java:603) at java.lang.Thread.run(Thread.java:722) The elasticsearchrealtime security group authorizes storm security group on every tcp,udp and icmp ports. The storm security group authorizes elasticsearchrealtime security group on every tcp,udp and icmp ports. Here are my current properties for the client : ################################### Cluster ################################### cluster.name: elasticsearchrealtime #################################### Index #################################### index.number\_of\_shards: 16 index.number\_of\_replicas: 1 ################################### Memory #################################### bootstrap.mlockall: true ################################## Discovery ################################## discovery.zen.ping.timeout: 5m discovery.type=ec2 discovery.ec2.groups: elasticsearchrealtime,storm discovery.ec2.ping\_timeout: 60s discovery.ec2.any\_group: true ################################# AWS Settings ################################### cloud.aws.region: us-east-1 cloud.aws.access\_key: xxxx cloud.aws.secret\_key: xxxx cloud.aws.s3.endpoint: [s3.amazonaws.com](http://s3.amazonaws.com) cloud.aws.ec2.endpoint: [ec2.us-east-1.amazonaws.com](http://ec2.us-east-1.amazonaws.com) gateway.s3.region: us-east-1 ################################### Client ################################### node.name: Elastic Search Realtime Client node.client: true node.data: false And here is the elasticsearch.yml file for one of my elasticsearch node : ################################### Cluster ################################### cluster.name: elasticsearchrealtime #################################### Index #################################### index.number\_of\_shards: 16 index.number\_of\_replicas: 1 ################################### Memory #################################### bootstrap.mlockall: true ################################## Discovery ################################## discovery.zen.ping.timeout: 5m discovery.type: ec2 discovery.ec2.groups: elasticsearchrealtime,storm discovery.ec2.ping\_timeout: 60s discovery.ec2.any\_group: true ####################### AWS Settings cloud.aws.region: us-east-1 cloud.aws.access\_key: xxxxx cloud.aws.secret\_key: xxxxxx cloud.aws.s3.endpoint: [s3.amazonaws.com](http://s3.amazonaws.com) cloud.aws.ec2.endpoint: [ec2.us-east-1.amazonaws.com](http://ec2.us-east-1.amazonaws.com) gateway.s3.region: us-east-1 node.name: Elastic Search Realtime 1 Any help would be greatly appreciated !

Is this a typo? discovery.type=ec2 Jörg -- You received this message because you are subscribed to the Google Groups "elasticsearch" group.

Nope, I just made a typo by translating my elasticsearch properties file here. 🙂 I use spring to inject all my properties into my Client. All the properties for the client are actually like this : node.name=Elastic Search Realtime Client node.client=true node.data=false cluster.name=elasticsearchrealtime #################################### Index #################################### index.number\_of\_shards=16 index.number\_of\_replicas=1 ################################### Memory #################################### # Elasticsearch performs poorly when JVM starts swapping=you should ensure that # it _never_ swaps. # # Set this property to true to lock the memory: # bootstrap.mlockall=true ################################## Discovery ################################## discovery.type=ec2 discovery.ec2.groups=elasticsearchrealtime,storm discovery.ec2.ping\_timeout=60s discovery.ec2.any\_group=true ####################### AWS Settings cloud.aws.region=us-east-1 cloud.aws.access\_key=xxxx cloud.aws.secret\_key=xxxx Thanks though!
