Issue with GPG Key retrieval which failed Hadoop Bigtop installation process

Question

I have followed the procedure from his link.

Starting from Step 1 to Step 2, the process ran successfully, but later at Step 3, I got into this error after downloading 616 MB and the error read as follows: 

#  Total                                           130 kB/s | 616 MB     80:52     
#    warning: rpmts_HdrFromFdno: Header V4 RSA/SHA1 Signature, key ID fa08b173: NOKEY
#    Retrieving key from https://dist.apache.org/repos/dist/release/bigtop/KEYS
#GPG key retrieval failed: [Errno 14] problem making ssl connection

I ignored that error thinking it would not have any effect. I then proceeded with rest of steps till 4.2 when I started getting the following error

#[root@localhost ~]# sudo /etc/init.d/hadoop-hdfs-namenode init
#sudo: /etc/init.d/hadoop-hdfs-namenode: command not found

On searching extensively I had come to realize that reinstalling i.e. running the command yum install Hadoop* would fix the issue, which I did and am getting this error.

#Total size: 198 M
#Is this ok [y/N]: y
#Downloading Packages:
#warning: rpmts_HdrFromFdno: Header V4 RSA/SHA1 Signature, key ID fa08b173: NOKEY
#Retrieving key from https://dist.apache.org/repos/dist/release/bigtop/KEYS
#GPG key retrieval failed: [Errno 14] problem making ssl connection

Am trying to fix this in both my Office System and my Home System.

Please help me fix this.

 I understood your problem,

I hope you can find the solution by following these steps:

1. Firstly, add the following text to the /etc/yum.repos.d/bigtop.repo file.

#[bigtop]
#name=Bigtop
#enabled=1
#gpgcheck=1
#type=NONE
#baseurl=http://www.apache.org/dist/bigtop/bigtop-1.1.0/repos/centos6/
#gpgkey=http://www.apache.org/dist/bigtop/bigtop-1.1.0/repos/GPG-KEY-bigtop

2. Next, try to install the necessary files again with the following:

#yum install hadoop\* mahout\* oozie\* hbase\* hive\* hue\* pig\* zookeeper\

This process must help you complete the Hadoop Big-Top Installation.
