Ambari not using available repos

[#1]

RHEL 7.2 on Power8

ambari-server-2.5.0.0-1096.ppc64le

Trying to install HDP 2.6.

For some reason the install (Install, Start, and Test part of the installation) is failing. It appears that it is having problems using the repos that are available to it. For example:

2017-08-09 18:35:03,706 - Skipping installation of existing package curl
2017-08-09 18:35:03,706 - Package['hdp-select'] {'retry_on_repo_unavailability': False, 'retry_count': 5}
2017-08-09 18:35:03,728 - Skipping installation of existing package hdp-select
2017-08-09 18:35:04,016 - Package['hadoop_2_6_0_0_598-yarn'] {'retry_on_repo_unavailability': False, 'retry_count': 5}
2017-08-09 18:35:04,177 - Skipping installation of existing package hadoop_2_6_0_0_598-yarn
2017-08-09 18:35:04,179 - Package['hadoop_2_6_0_0_598-mapreduce'] {'retry_on_repo_unavailability': False, 'retry_count': 5}
2017-08-09 18:35:04,202 - Installing package hadoop_2_6_0_0_598-mapreduce ('/usr/bin/yum -d 0 -e 0 -y install hadoop_2_6_0_0_598-mapreduce')

So it cannot install hadoop_2_6_0_0_598-mapreduce. But if I go to the command line, I can install this:

Complete!

I don't understand why Ambari is having such a problem using the HDP and HDP-Utils repositories. They are configured like this:

[root@hdplab80 yum.repos.d]# cat HDP.repo
[HDP-2.6]
name=HDP-2.6
baseurl=http://private-repo-1.hortonworks.com/HDP/centos7-ppc/2.x/updates/2.6.0.0-598

path=/
enabled=1
gpgcheck=0[root@hdplab80 yum.repos.d]# cat HDP-UTILS.repo
[HDP-UTILS-1.1.0.21]
name=HDP-UTILS-1.1.0.21
baseurl=http://public-repo-1.hortonworks.com/HDP-UTILS-1.1.0.21/repos/ppc64le

path=/
enabled=1

Can anyone spot what is wrong here? Essentially, Ambari is not using the repos available to it, I think.

Thanks in advance.

Marked the yum.conf issue as the resolution.

For the libtirc-devel issue the fix was:

yum-config-manager --enable rhel-7-for-power-le-eus-optional-rpms
yum-config-manager --enable rhel-7-rhel-7-for-power-le-optional-rpms

Thanks ever so much to @Jay SenSharma and @Geoffrey Shelton Okot for all your help on this. Cluster install is currently at 19%.

One of my thread has similar issue:

for your query related to:

Error: Package: hadoop_2_6_2_0_205-hdfs-2.7.3.2.6.2.0-205.ppc64le (HDP-2.6)
