DEVELOPMENT_MODE_ENABLED_CWOBJ0047=CWOBJ0047I: Development mode is enabled for one or more MapSets for ObjectGrids: {0}. For a production deployment, set the development mode attribute in the deployment policy file to false.
Explanation
Development mode allows primary and replica shards for the same partition to be placed on the same machine. When using one or two machines to develop code, this behavior is acceptable. However, when running in production, allowing placement of a primary and its replicas on the same machine risks data loss in case of whole machine failure.
User response
If you are in production phase or test phase consider changing development mode to false. The default is true. Otherwise, no action is required. See the Deployment policy descriptor XML file article in the information center for more information about the developmentMode setting.
