>
> Whenever user adds service to Ambari, the value "hadoop.proxyuser.hcat.hosts"
> got changed. 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
