| Summary: | MapReduce is a popular, open source programming paradigm to handle big data which is an industry standard large scale data processing system used by many companies like Yahoo, Google, Facebook, etc. The YARN framework uses low resource fairness algorithms such as FIFO, Capacity, Fair, DRF scheduler, whereas these schedulers are not suitable for heterogeneous Hadoop clusters. Therefore, an Enhanced Combined Regression Ranking (eCRRYARN) algorithm was proposed to enhance resource fairness. The proposed algorithm uses linear regression model to estimate the expected resources to be availed by the tenants. The order ranking is given to the estimated resource and the resources shared as per the ranking provided. Hence, the Hierarchical Hadoop Cluster Resource Sharing (HHCRS) algorithm has been adopted for hierarchical distributed cluster aiming to design a cost effective cluster for organization which is spread across the globe.
