Hortonworks Ambari Installation on Ubuntu 14.04

Hortonworks Installation on Ubuntu 14.04

Hortonworks Data Platform is designed as an Open source platform that facilitates integrating Apache Hadoop with an enterprise’s existing data architectures.

 

Here I’m using 3 machines.

One Namenode – Master

Two Datanodes – Slave1 & 2

 

Pre-Installation steps

 

1. Create a new user in all nodes with sudo permission.

Command to create user

# adduser user

 

To give sudo privileges to normal users, use below command by changing the user.

#echo “user ALL=(ALL) NOPASSWD: ALL” | sudo tee/etc/sudoers.d/user

 

2.  Allow SSH for that user (All nodes)

 

3. Create password-less SSH into that user

Login into master node

# ssh-keygen [Only in master node]

Copy the public key to all nodes using the command

# ssh-copy-id user@x.x.x.x

Change the directory:

# cd /~ssh

Copy private key to authorized_keys:

# cat id_rsa >> authorized_keys

Change permisions: # chmod 600 authorized_keys

# chmod 700 /~.ssh

 

4. Install ntp:

# apt-get install ntp ntpdate

Edit /etc/ntp.conf according to the timezone

I’m using Asia region for example: Replace the timezone in ntp.conf file by these lines.

        server 1.in.pool.ntp.org

server 1.asia.pool.ntp.org

server 2.asia.pool.ntp.org

To use the specific time zone, go to the link

 

5. Disable Transparent huge pages (THP)

Install hugepages :

# apt-get install hugepages

Disable pages :

# hugeadm –thp-never

Check whether it is disabled or not using command

# cat /sys/kernel/mm/transparent_hugepage/enabled

output : [never]

 

6. Edit /etc/hosts by adding all node IP and FQDN

Format: IP FQDN Hostname

 

7. Verify by giving the command:

# hostname -f

Output should be FQDN

 

8. Disable firewall

# ufw disable
