[SOLVED] Ambari 2.4.0.1 fails to install HDP 2.5.0.0: yum repo and version mismatch

benoit — Wed, 07 Sep 2016 14:59:24 GMT

I'm doing a fresh install of Ambari 2.4.0.1 and HDP 2.5.0.0. Ambari is working fine, I can go through the wizard and select the stack (2.5.0.0), do a manual registration of my hosts, assign the components (master/slave) and start the deployment.

The "Install, Test and Start" phase fails with the following stacktrace:

Traceback (most recent call last):

resource_management.core.exceptions.Fail: Execution of '/usr/bin/yum -d 0 -e 0 -y install hadoop_2_4_2_0_258' returned 1. Error: Nothing to do

It fails installing hadoop_2_4_2_0_258 while I did select HDP 2.5.0.0 stack ?!?!

Looking at the yum repo set during the manual registration, it makes sense that version 2.4.2.0 is not found, since it's properly pointing to 2.5 repo:

$ cat /etc/yum.repos.d/HDP.repo
[HDP-2.5]
name=HDP-2.5
baseurl=http://public-repo-1.hortonworks.com/HDP/centos7/2.x/updates/2.5.0.0


path=/
enabled=1

Why are the wrong version tried to be installed on the nodes?

Thanks

Replying to my own question 🙂

For some reason, hdp-select was partially installe with a version 2.4.2.0.

Running a "yum upgrade hdp-select" on all the nodes did fix the problem of version mismatch.

Just ran into this one myself. Looks like Ambari parses the output of hdp-select to determine the full package name to install:

rpm -q --queryformat '%{version}-%{release}' hdp-select | sed -e 's/\.el[0-9]//g'
