"Currently Custom Dns is not supported in HDInsight."
We tested the configuration (HDInsight cluster with Windows/Linux, Hadoop and HDInsight 3.2 & 3.4) on new portal and got the error.
However, if we use the classic portal, and create the classic virtual network with the custom DNS server registered, and then specify the virtual network during Windows version of HDInsight cluster provisioning, it seems that we can start the provision.
But we use Linux Hadoop and cannot provision Linux version of Hadoop with custom DNS in virtual network, it is not supported in the old classic portal.
Is there any suggestion or specific schedule for this?
