However, the processing of the join queries come with higher overhead since all the tables or files involved in the process have to be considered. It can easily be imagined how much the overhead could become when data contained in such tables/files is big data. The use of indexing on Hadoop and its abstractions have resulted in improved performance when processing queries. However, even with the use of some of the indexing approaches, the processing of join query indicates higher overhead, except when the amount of data to processed is reduced by the indexing techniques before the query processing even get started. One indexing technique that ensures this, is the InputSplit based index. This paper showcases how InputSplit based indexing can be implemented in Hadoop MapReduce as well the experimental results of running a join query using such index. The results show at least 50 reduction in runtime when compared to both normal Hadoop MapReduce and Clustered Index based on blockIds query processing approaches. © 2019 IEEE. date: 2019 publisher: Institute of Electrical and Electronics Engineers Inc. official_url: https://www.scopus.com/inward/record.uri?eid=2-s2.0-85084312161&doi=10.1109%2fICCSCE47578.2019.9068559&partnerID=40&md5=3d99a4359ec8de94a0728a053c23d1ee id_number: 10.1109/ICCSCE47578.2019.9068559 full_text_status: none publication: Proceedings - 9th IEEE International Conference on Control System, Computing and Engineering, ICCSCE 2019 pagerange: 131-135 refereed: TRUE isbn: 9781728135007 citation: Ahmad, R. and Zakaria, M.N. and Abdullahi, A.U.
