    <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.

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;The NullPointerException indicates that the "spec" (URL location) is not setup correctly.  Hence it is not able to find the Repo which is causing this error.&lt;/P&gt;&lt;PRE&gt;01 Feb 2018 11:35:53,591WARN [ambari-client-thread-2234] ServletHandler:561 - Error Processing URI: 
/api/v1/stacks/HDP/versions/2.6/operating_systems/redhat7/repositories/HDP-UTILS-1.1.0.22  - (java.lang.RuntimeException) java.lang.NullPointerException&lt;/PRE&gt;&lt;P&gt;.&lt;/P&gt;&lt;P&gt;So can you please try enabling the DEBUG on the ambari-serevr by editing the "/etc/ambari-server/conf/log4j.properties" file and edit the INFO to DEBUG in the following line:&lt;/P&gt;&lt;PRE&gt;# grep 'log4j.rootLogger' /etc/ambari-server/conf/log4j.properties
log4j.rootLogger=INFO,file&lt;/PRE&gt;&lt;P&gt;.&lt;/P&gt;&lt;P&gt;Then restart the ambari-server and then once you get the same error please grep the string "readFrom spec" in the log and then share it with us.&lt;/P&gt;&lt;PRE&gt;# grep 'readFrom spec' /var/log/ambari-server/ambari-server.log&lt;/PRE&gt;&lt;P&gt;.&lt;/P&gt;&lt;P&gt;Then from ambari-server Host can you try doing a "wget" to the repo to see if you are able to do it?    This will isolate any Firewall or Proxy Server issue.&lt;/P&gt;&lt;PRE&gt;# wget &lt;A href="http://1.1.1.1/repo/HDP-UTILS/repos/centos7/repodata/repomd.xml" target="_blank"&gt;http://1.1.1.1/repo/HDP-UTILS/repos/centos7/repodata/repomd.xml&lt;/A&gt;&lt;/PRE&gt;&lt;P&gt;Reference:  &lt;A href="https://github.com/apache/ambari/blob/release-2.6.1/ambari-server/src/main/java/org/apache/ambari/server/controller/internal/URLStreamProvider.java#L175-L179" target="_blank"&gt;https://github.com/apache/ambari/blob/release-2.6.1/ambari-server/src/main/java/org/apache/ambari/server/controller/internal/URLStreamProvider.java#L175-L179&lt;/A&gt;&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>
