Hadoop 2 to Hadoop 3 Rolling Upgrade feasibility
Hi team, While I am checking on feasible upgrade plans for this major upgrade, A quick check if someone was able to perform a successful rolling upgrade from Hadoop 2 to Hadoop 3. I have gone through a couple of articles online which are suggesting to opt for Express Upgrade and avoid Rolling upgrade. A quick check if someone was able to successfully do a rolling upgrade in recent years. References I have gone through: https://blog.cloudera.com/upgrading-clusters-workloads-hadoop-2-hadoop-3/ https://cwiki.apache.org/confluence/display/HADOOP/Hadoop+2.x+to+3.x+Upgrade+Efforts https://www.adaltas.com/en/2018/07/25/clusters-workloads-migration-hadoop-2-to-3/ Any leads/responses are appreciated. -- Thanks, Nishtha Shah
