1)Please define actual size and performance numbers that you encountered. Ans. Data Volume Time elapsed for TEZ Average Time MR Time elapsed for MR Average Time for TEZ 1900 records 46.350 secs 41.626 secs 63.666 secs 56.176 secs 40.341 secs 55.633 secs 38.189 secs 49.230 secs 91914 records 32.049 secs 32.097 secs 52.920 secs 51.236 secs 32.088 secs 49.030 secs 32.156 secs 51.760 secs 993168 records 850.01 secs 861.781 secs 611.625 secs 635.781 secs 865.230 secs 691.751 secs 872.110 secs 672.285 secs 868.995 secs 567.466 secs 2)Clarify what test beds you are referring and how did you use them? Ans. In above statistics table: In Operation 1 is a creating lateral view on a small data set. In Operation 2 is joining 3 tables of intermediate data volume. In Operation 3 is joining 4 tables of large data volume in inner query and aggregation happening on top of that. 3)Clarify what is the type of test case you execute? It is important to clarify because some tests can be disk I/O intensive, others can be memory intensive. 1.Ans. Above jobs ran in parallel i.e. 10 jobs in parallel on TEZ mode and 10 jobs in parallel on MR mode. 2.Above results are output of multiple test iterations and performed on different test beds. ...
