Hadoop Error Hadoop Master cannot start the Slave with different user or Slave with different user failed to start by Hadoop Master node

Question

 In my another scenario, I tried with set-up Hadoop multi-node cluster with different user for Master and Slave.

 In my case:

Master : hduser
Slave1 : hduser
Salve2 : root

while i'm starting Master node by,

$start-dfs.sh

Can anyone solve the issue?

Hi,

You can use these commands to get out of this issue.

• Start Salve daemons manually by start-dfs.sh (OR )
• bin#./hadoop-daemon.sh start datanode  

 Hadoop framework does not require ssh and that the DataNode and TaskTracker daemons can be started manually on each node. So need not require each salve configure the same path​.
