This would allow to&nbsp;<br>\nsave a lot of disk capacity in needed by project hosted in CERN IT Hadoop service. The goal of&nbsp;<br>\nthe project is to evaluate the new features of Hadoop 3 and make an assessment of its readiness&nbsp;<br>\nfor production systems (this includes installation and configuration of a test hadoop3 cluster,&nbsp;<br>\ncopying production data to it, conducting multiple performance test on the data). &nbsp;</p>",
