I install Watcher as i see in the "getting-started" docs,
bin/plugin -i elasticsearch/watcher/my\_key
and service elasticsearch restart
I get the following error "elasticsearch dead but subsys locked" and nothing worked even this link did not help me...

elasticsearch came back to life only when i uninstall watcher

In the log file i see
" Error injecting constructor, java.lang.NoSuchMethodError: org.elasticsearch.discovery.zen.ZenDiscovery.(Lorg/elasticsearch/common/settings/Settings;Lorg/elasticsearch/cluster/ClusterName;Lorg/elasticsearch/threadpool/ThreadPool;Lorg/elasticsearch/transport/TransportService;Lorg/elasticsearch/cluster/ClusterService;Lorg/elasticsearch/node/settings/NodeSettingsService;Lorg/elasticsearch/cluster/node/DiscoveryNodeService;Lorg/elasticsearch/discovery/zen/ping/ZenPingService;Lorg/elasticsearch/discovery/zen/elect/ElectMasterService;Lorg/elasticsearch/discovery/DiscoverySettings;)V

Hmm that is odd.
I'll point the Watcher and the AWS plugin team here and maybe they can assist.

What ES version are you on?
What version of the AWS plugin is installed?

Version 2.4.1 isn't compatible with ES 1.5, you need to install version 2.5.1:
> **[elastic/elasticsearch-cloud-aws](https://github.com/elastic/elasticsearch-cloud-aws)**
>
> AWS Cloud Plugin for Elasticsearch. Contribute to elastic/elasticsearch-cloud-aws development by creating an account on GitHub.
Can you run the following command:
bin/plugin install elasticsearch/elasticsearch-cloud-aws/2.5.1
