Migrating your clusters and workloads from Hadoop 2 to Hadoop 3

Migrating your clusters and workloads from Hadoop 2 to Hadoop 3

Tuesday, June 19
2:50 PM - 3:30 PM
Meeting Room 211A/B/C/D

The Hadoop community announced Hadoop 3.0 GA in December, 2017 and 3.1 around April, 2018 loaded with a lot of features and improvements. One of the biggest challenges for any new major release of a software platform is its compatibility. Apache Hadoop community has focused on ensuring wire and binary compatibility for Hadoop 2 clients and workloads.

There are many challenges to be addressed by admins while upgrading to a major release of Hadoop. Users running workloads on Hadoop 2 should be able to seamlessly run or migrate their workloads onto Hadoop 3. This session will be deep diving into upgrade aspects in detail and provide a detailed preview of migration strategies with information on what works and what might not work. This talk would focus on the motivation for upgrading to Hadoop 3 and provide a cluster upgrade guide for admins and workload migration guide for users of Hadoop.
