I have created the new stack named "test" in ambari. Now I wanted to use the custom-services available in the ambari -server into the new stack "test". Like how HDP extended the common-services (i.e,HDFS) from the version 2.0.6, we have also extended the custom-services(HDFS) in the metainfo.xml belowm /var/lib/ambari-server/resources/stacks/TEST/1.0/services/HDFS" <metainfo>
<schemaVersion>2.0</schemaVersion>
<services>
<service>
<name>HDFS</name>
<extends>common-services/HDFS/2.1.0.2.0</extends>
</service>
</services>
</metainfo> When we try to install the HDFS from ambari host(web-ui) we could not succeed and the ambari-server.log for your reference, request you to help to overcome this scenario. turning DefaultStackAdvisor implementation
