optimization of left outer join operation over big data using apache hadoop and apache hbase

摘要

optimization of the left outer join operation over big t) ata using apache hadoop and apache hbase operation and communication model between the apache hadoop (to be referred to as hadoop) and apache hbase (to be referred to as hbase) middlewares running on a cluster to allow, in just one mapreduce job, left outer join operations on big data stored in hbase tables containing only one data column and one access key. The invention proposed herein is applicable to any field of the industry where large volumes of data are stored on hbase middleware and are processed on hadoop middleware, today both industry standard in big data storage resolution and processing.
