I have a old cluster with CentOS 6.1 (64 Bit). Can I install latest version of CDH (CDH 5.0.1) in it ? Will it support future upgrades in the coming years ?
I had bad luck with 6.1 so I updated my cluster systems to CentOS 6.6/RedHat 6.6 or Scientific Linux 6.6 and they all worked without issues.
I would upgrade your OS or version manipulation.
