Hi all, the instructions given in the article avoid to mention a setup pre-requisite which is "Installing VirtualBox Guest Additions" on the guest machine, that is to say installing it on our CentOS based HDP Sandbox VM. Simple ? .... Not really ! The devil is inside the details. In Virtualbox documentation Chapter 4 Guest Additions, it is said; So we have a pre-requisite of our pre-requisite, which consists of "preparing [our] guest for building external kernel modules" And our HDP 2.6.4 doesn't seem ready: the running kernel (4.4.x id I'm right) and the kernel-devel and kernel-headers versions do not match), which is a condition that is checked during the installation process. Trying to update the kernel-devel/kernel-headers to match the 4.4.x version, I ended up with a conflict and I was unable to update the kernel-headers with the 4.4.x version. Removing the package (before reinstalling the 4.4.x version) doesn't seem an option neither, because of its dependancies: At the end, I didn't succeed in mouting shared folders into my HDP 2.6.4. Any help will be very appreciated.

Thank you, it also worked for me. I was trying to connect to hive with a CLI interface (/usr/bin/hive or /usr/bin/beeline), and using the URL connexion show in the Ambari / Services / Hive / Summary interface, the connexion was refused. Using jdbc:hive2://sandbox.hortonworks.com:10000/default, it works This JIRA page can really help: HiveServer2 Clients. It explains the Connection URL Format and explicits some default (like the default port = 1000) Phil ... View more
