Integrate Elasticsearch with HDFS
Elasticsearch is a distributed, RESTful search and analytics engine that allows you to search and analyze your data in real time. It centrally stores your data so that you can use it to draw key insights and improve your long-term analytics.
HDFS is a Java-based file system that provides scalable and reliable data storage, and it was designed to span large clusters of commodity servers. HDFS has demonstrated production scalability of up to 200 PB of storage and a single cluster of 4500 servers, supporting close to a billion files and blocks.
