Subject General Query : Master & DataNode start
Date Tue, 03 Jan 2017 04:16:28 GMT
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 ?
