Hi All, As part of my lab exercise i am doing a self study of Hadoop. i have cloned Master to 2 Datanodes as Datanode 1 and Datanode 2.
Two Querys from Real Scenarios : 1. If Master is Up and running, DataNodes are stopped/suspended, will there be any communication channel from Datanode to Master or will the replication works ? 2.. Is there a need to run this command start-dfs.sh or start-all.sh in master as well as datanodes ? Thanks, Renjith
