Improvising Data Locality and Availability in Hbase Ecosystem

In this paper, the authors try to represent the importance of data locality with the HBase architecture. HBase has a dynamic master slave architecture but the emphasis on data locality, i.e. getting the logic or processing near to the data is the major phenomenon followed for better and efficient performance. Data locality is valid as every region server has the information of every data blocks located in respective regions but what if the region server crashes or the region server is restarted or the regions are randomly re-distributed with all the region servers due to load balancing, then data locality is completely lost during that time.
