>> We can't add Slider automatically for them since they have to pick the hosts. I meant of just creating slider service and slider client service component. Creation of Host components can be delayed when user chooses the host for hive interactive component when turning ON "Interactive query" flag. At that point of time we will create host component for hive interactive and its host scope dependencies (slider client, tez client, yarn client and hdfs client) on the selected host. At the minimum as I mentioned above we can ask the user to install slider service using Add service wizard when user turns on "interactive query" flag to use this feature of Hive service. - Jaimin ----------------------------------------------------------- This is an automatically generated e-mail.
