I am gonna adding a new hosts in existing cluster ....All Network Process are done successfully ...after then did't register new hosts by AMBARI....
hdp version details : hdp 2.6 with ambari 2.6
Os - centso7
Please Suggest How to do ,
Your Help is Highly appreciated .
If you want to setup a multi node cluster then please refer to the following Hortonworks Youtube Video
Hadoop Series- Part1 Multinode Hadoop Cluster Installation using Ambari : https://www.youtube.com/watch?v=wHaVBoLwzwU
Regarding the failure which you posted in your last comment is happening due to:
File "/var/lib/ambari-agent/tmp/os_check_type1546513757.py", line 40, in main raise Exception("Local OS is not compatible with cluster primary OS family. Please perform manual bootstrap on this host.") Exception: Local OS is not compatible with cluster primary OS family. Please perform manual bootstrap on this host.
Looks like you are trying to register a new host which has slightly different OS version/type.
In that case we will suggest you to try using Manual Host installation & registration instead of doing it via Ambari UI. You can find the instructions to Manually Register Ambari Agenrt here:
The problem seems to be the incorrect "SSH Private Key". Based on screenshot "screenshot-from-2018-12-28-18-23-15.png" looks like you are pasting the "Public" key content there instead of "Private Key" of the host "hdpnode1.hortonworks.com"
For example the following will be the Private Key: "~/.ssh/id_rsa" adn the content of private key file looks something like following which BEGIN and END marks:
-----BEGIN RSA PRIVATE KEY----- ANCDEFGHIJKLMNOPoCUhgGazht5XrPbvkcD ....... QRSTUVWXYZasdoeruoijlcsd,fns,cjsdklfjo= -----END RSA PRIVATE KEY-----
Usually Public key file name is "~/.ssh/id_rsa.pub"
Also the Ambari API call is showing 404 because you will need to replace the "$name" with your clustername. You can get your ambari cluster name using the following API call.
Hi Sir Thanks For the reply ...
Sir , You Are Absolutely Right , It is the first host in the cluster ......
