Ambari HDP 2.6 multinode Installation fails at last step

New Contributor

I'm trying to install HDP 2.6 on 16 nodes (2 master nodes and 14 slaves) using Ambari wizard. After many challenges it is completed, but not enough successfully - all nodes get orange with "Warnings encountered". All slave nodes have only warning related to NodeManager Start

I'd highly appreciate any help on fixing this issue.

Here are some outputs and error messages from different nodes:

==== MasterNode1

@Abzetdin Adamov

Can you manually start the node manager

su -l yarn -c "/usr/hdp/current/hadoop-yarn-nodemanager/sbin/ start nodemanager"

Can you also check whether this directory exists

1) node manager is running

2) this folder does not exit not in master not in slaves

Do you think it will help if I create it

Additionally on Ambari UI -
