Elasticsearch-hadoop is a project that integrates Hadoop and elasticsearch in depth, and is also a subproject maintained by ES officials, by implementing input and output between Hadoop and Es, You can read and write data from the ES cluster in Hadoop, giving full play to the benefits of map-reduce parallel processing, and bringing real-time search possibilities to Hadoop data.Project website: http://www.el

Label:Hive Architecture:is the Data warehouse infrastructure built on top of Hadoop. Similar to the database, except that the database focuses on some transactional operations, such as modify, delete, query, in the database this piece occurs more. The Data Warehouse is primarily focused on querying. For the same amount of data in the database query is relatively slow, in the Data Warehouse query efficiency is relatively fast.
