HDP 2.5 Installation problem in CentOS7

[#1]

Team,

I am getting error during HDP 2.5 installation in Centos 7:

resource_management.core.exceptions.Fail: Execution of '/usr/bin/yum -d 0 -e 0 -y install snappy-devel' returned 1. Error: Package: snappy-devel-1.0.5-1.el6.x86_64 (HDP-UTILS-1.1.0.21)
           Requires: snappy(x86-64) = 1.0.5-1.el6
           Installed: snappy-1.1.0-3.el7.x86_64 (@centos7)
               snappy(x86-64) = 1.1.0-3.el7
           Available: snappy-1.0.5-1.el6.x86_64 (HDP-UTILS-1.1.0.21)
               snappy(x86-64) = 1.0.5-1.el6
 You could try using --skip-broken to work around the problem
 You could try running: rpm -Va --nofiles --nodigest

Please suggest a solution to overcome this issue.

why installation engine is checking el6 rpm rather than el7 rpm?

You seems to be hitting the issue that is reported in: http://docs.hortonworks.com/HDPDocuments/Ambari-2.2.2.0/bk_ambari_troubleshooting/content/_resolving...

3.10. Problem: DataNode Fails to Install on RHEL/CentOS 7.

During cluster install, DataNode fails to install with the following error:  
resource_management.core.exceptions.
            Fail: Execution of '/usr/bin/yum -d 0 -e 0 -y install snappy-devel' returned 1.
            Error: Package: snappy-devel-1.0.5-1.el6.x86_64 (HDP-UTILS-1.1.0.20)
            Requires: snappy(x86-64) = 1.0.5-1.el6
            Installed: snappy-1.1.0-3.el7.x86_64 (@anaconda/7.1)
            snappy(x86-64) = 1.1.0-3.el7
            Available: snappy-1.0.5-1.el6.x86_64 (HDP-UTILS-1.1.0.20)
            snappy(x86-64) = 1.0.5-1.el6

 3.10.1. Solution:

 Hadoop requires the snappy-devel package that is a lower version that what is on
              the machine already.  Run the following on the host and retry.
yum remove snappy
yum install snappy-devel

.

In General:

This seems to be because of incorrect version of snappy-devel On CentOS7/Redhat7. So as a workaround you will need to try the following:

yum remove -y snappy 
yum install -y snappy-devel

.

I installed HDP 2.5 on Centos 7.2 with no issues, make sure it's the correct repo and follow the prereqs for install

resolved my issue by removing snappy as suggested by JSS
