The apigatewayUtil.bat create backup command fails to execute with the following BeanCreationException error:

org.springframework.beans.factory.BeanCreationException: Error creating bean with name 'elasticSearchClient' defined in URL file:E:/ESB/WM/IntegrationServer/instances/default/packages/WmAPIGateway/config/resources/beans/gateway-es-store.xml : Invocation of init method failed; nested exception is No NodeAvailableException[None of the configured nodes are available: [

Resolution:

Ensure that you have provided a valid elasticsearch hostname and port number in the config.properties file located at SAGInstallDir\IntegrationServer\instances\default\​packages\WmAPIGateway\config\resources\elasticsearch.

When I attempt to backup the API Gateway database with the following commands, they fail:

This is because of the path.repo specified in the elasticsearch.yml. The path.repo was pointing to a local file instead of a shared file location.

Resolution:

In the Elasticsearch cluster environment, it is mandatory to specify a shared file location as path.repo in the elasticsearch.yml located at SAGInstallDir\InternalDataStore\config.
