@Geoffrey Shelton Okot I've tried as you suggested but still the same error persist while installing NN in new server. Please could you let me know from which location its referring the old version.

Thanks.

@Saravana V,

Check the folders inside /usr/hdp folder. If you have folder with name "2.6.1.0-129", try moving it to some other directory and retry the operation.

Please "Accept" the answer if this helps 🙂

@Aditya Sirna There is no such dir inside /usr/hdp/. Does it refer the old version somewhere from cache.

$ ls -la /usr/hdp/

@Saravana V,

Can you try running the below command and check the output

hdp-select status hadoop-hdfs-namenode

Also run the below command on the both the namenode hosts and see if it passes

yum reinstall -y hadoop*

@Aditya Sirna

Great 🙂 this worked for me. Not sure where I was stuck up, still I want to know why it was referring previous version. By the way, thanks for your support which really appreciated.

Thanks.
