This will not cause a performance boost directly to all queries or jobs but will allow the cluster the scale and improve the overall cluster performance I.E. you can now run twice as many jobs or the same out of jobs but on double the amount of data. There are other factors for Hive performance as well such as the metestore and HS2. Mon, 10 Apr 2017 21:10:47 GMT mbigelow 2017-04-10T21:10:47Z
