Re-adding nodes to Intel hadoop clusters

[dafridgie]

Hi, I've been reading the optimization guide and found the section on setting a high inode count for the filesystem and wanted to implement it.

Firstly, i used intel manager to remove the nodes form the cluster

then i unmounted the drives , formatted and remounted

I then trierd adding them back to the hadoop cluster and I get this error in the add node task window of intel manager:

I've anonomized the ip and server names.

It seems that on a node re-add afer removal there is a certificate problem, any ideas on how to resolve this ?

problem solved!

I found the cause of the error to be that i had disabled SSH access for root on the internal cluster interfaces. Re-enabling this resolved the problem
