My Configuration

3 Node Cluster

/etc/hosts as 

127.0.0.1 localhost localhost.localdomain localhost4 localhost4.localdomain4
::1 localhost localhost.localdomain localhost6 localhost6.localdomain6
192.168.1.5 base.hadoopdomain.com hadoop1
192.168.1.6 node1.hadoopdomain.com hadoop2
192.168.1.7 node2.hadoopdomain.com hadoop3

IPV6 Disabled, IP are DHCP assigned and same as shown above, SELINUX disabled, followed all other steps as mentioned anywhere else. 

Incorrect IP on Python gethostname Command

python -c 'import socket; print socket.getfqdn(), socket.gethostbyname(socket.getfqdn())'
node2.hadoopdomain 198.105.254.228

The FQDN is right but IP is incorrect. its the same on all the nodes. 

Python says IPV6 as true

python -c 'import socket; print socket.has_ipv6'
True

same on all nodes. 

Appreciate your assitance.

Hi,
During the process of installation of cloudera manager, it get stuck on the 4th step (Installing Selectecd Parcels) and don't go on. The only clue I got is a message in the cloudera-scm-server.log log as follow:
2015-03-06 17:53:52,811 WARN ParcelUpdateService:com.cloudera.parcel.components.ParcelInstallerImpl: Attempted to install an unknown parcel CDH-5.3.1-1.cdh5.3.1.p0.5
Is there any action I should take to clarify the problem and go on?
Thanks

Samuel,

Can you try a ping from your node  - ping google.com

see if your node has access to internet.

Cloudera Manager during its installation process refers to Interenet to download various components.

Solved the issue,

It was the etc/hosts file causing issue.

Had to add the highlighted red text on the etc/hosts file

127.0.0.1   localhost.hadoopdomain localhost
::1         localhost.hadoopdomain localhost
127.0.0.1   localhost.localdomain localhost
127.0.0.1   localdomain localhost
192.168.1.8 base.hadoopdomain.com base base.hadoopdomain
192.168.1.6 node1.hadoopdomain.com node1 node1.hadoopdomain
192.168.1.7 node2.hadoopdomain.com node2 node2.hadoopdomain
