We should either prompt user if he is comfortable with the > changes, or let it alone. In customer environment, this values got changed to > something different when he adds Accumulo, Kafka and Knox. > After the initial install, the property hadoop.proxyuser.hcat.hosts = '*' > Then, Accumulo was installed using the Ambari Add Service Wizard. After > Accumulo was installed, the value of hadoop.proxyuser.hcat.hosts was > 'baron2.example.org' (FQDN of second master node) > Then, Kafka was added using the Ambari Add Service Wizard. After Kafka was > installed, the value of hadoop.proxyuser.hcat.hosts was > "baron1.example.org,baron2.example.org". > Then Knox was added using the Ambari Add Service Wizard. After Knox was > installed, the value of hadoop.proxyuser.hcat.hosts was 'baron1.example.org'. > At this point the Hive Service Check failed with an "Unauthorized connection > for super-user: hcat" error. " > In the support lab, value was set to hcat host after cluster installation. I > changed it to * to match customer environments, and every time I add services > it changed it back to hcat host > BUSINESS IMPACT: If customer is using Ambari view or Hue, changing this > configuration will break them -- This message was sent by Atlassian JIRA (v6.3.4#6332)
