      <title>Trouble with installing HDP 2.6.4 through Ambari using local repo</title>

      <description>&lt;P&gt;I am trying to install HDP 2.6.4 version through Ambari 2.6.1 - the Ambari GUI is up and running.&lt;/P&gt;&lt;P&gt;Created the local repo in another server. Able to get to the local repos from the browser using the Base URLs.&lt;/P&gt;&lt;P&gt;In Ambari Cluster install wizard, selected following as local repos:&lt;/P&gt;&lt;P&gt;HDP-2.6 - &lt;A href="http://1.1.1.1/repo/HDP/centos7/2.x/updates/2.6.4.0/" target="_blank"&gt;http://1.1.1.1/repo/HDP/centos7/2.x/updates/2.6.4.0/&lt;/A&gt;&lt;/P&gt;&lt;P&gt;HDP-2.6-GPL -http://1.1.1.1/repo/HDP-GPL/centos7/2.6.4.0-91&lt;/P&gt;&lt;P&gt;HDP-UTILS-1.1.0.22 - &lt;A href="http://1.1.1.1/repo/HDP-UTILS/repos/centos7/" target="_blank"&gt;http://1.1.1.1/repo/HDP-UTILS/repos/centos7/&lt;/A&gt;&lt;/P&gt;&lt;P&gt;But with this, the Ambari throws Server Error (500). &lt;/P&gt;&lt;P&gt;I have tried adding the hostnames in /etc/hosts and tried with FQDN names as well.&lt;/P&gt;&lt;P&gt;I am a beginner and any help is appreciated. Thanks!&lt;/P&gt;</description>

If yes then please share the VDF file as well.&lt;/P&gt;</description>

      <description>&lt;P&gt;&lt;A rel="user" href="https://community.cloudera.com/users/65206/jayanthimalajayakumar2.html" nodeid="65206"&gt;@Jay&lt;/A&gt;&lt;/P&gt;&lt;P&gt;Sometimes it happens that the "wget" works because the host has some global proxy settings defined (like in ~/.bash_profile, /etc/profile, /etc/wgetrc  file ,  However ambari is a java process and it requires oproxy settings done via JVM properties. As described in  &lt;A href="https://docs.hortonworks.com/HDPDocuments/Ambari-2.6.1.0/bk_ambari-administration/content/ch_setting_up_an_internet_proxy_server_for_ambari.html" target="_blank"&gt;https://docs.hortonworks.com/HDPDocuments/Ambari-2.6.1.0/bk_ambari-administration/content/ch_setting_up_an_internet_proxy_server_for_ambari.html&lt;/A&gt;&lt;/P&gt;&lt;PRE&gt;-Dhttp.proxyHost=&amp;lt;yourProxyHost&amp;gt; -Dhttp.proxyPort=&amp;lt;yourProxyPort&amp;gt;&lt;/PRE&gt;&lt;P&gt;So can you please check your ambari server host if there is any Http Proxy setting done at global level?   If yes then we will need to add the proxy setting in "/var/lib/ambari-server/ambari-env.sh" file as well.&lt;/P&gt;</description>
