Special help needed!
I read all the documentation that I found only on the net (StackOverflow etc. but github), nothing helped.
I’m trying to connect to hive(hue) in python from my computer, each for our scripts is:

We’re having a problem using Anaconda for the Natural connect hive. Hive version – 3.1.0 Ambari 2.7.4, multi-node cluster. Connecting Python Hive to RHEL Serveryes it worked fine. But the environment does not mean it passes, Anaconda Windows10’s is connected. Sorting Conda Est 4.9.0. Actual error below

We have a VPN where we include a Windows Server box and a Hortonworks based hadoop distribution installed on several of these nodes data from Redhat.
vbulletin null in python is installed on the windows machine and we are also trying to make hive access tables available in the cluster, said hadoop.Top
on the Hive port number 10000, physical requests are listening.
From an ODBC windows window, it works fine on the Dit network with transport, but the python script mentioned below failed to execute an error.
in case I installed some mandatory systems required for hive connections below;
Please find the code:

Startup Steps For Any Type Of Windows
When you press the button, the power-up process goes through several stages. We will move from and to solving problems that usually arise stages on. Let's find them first and the text will appear during the de.start

| Phase | Launch | BIOS | uefi |
| 1 | Preliminary (boot code) | uefi firmware | |
| 2 | Windows Boot Manager | %SystemDrive%\bootmgr | \EFI\Microsoft\Boot\bootmgfw.efi |

| 4 | Windows NT operating system kernel | %SystemRoot%\system32\ntoskrnl.exe |
1] You are preloading
When you press the power button, the computer will run a POST or firmware and load the firmware settings. If the presence of the system hard drive is checked, start for the following status. This is indicated by the MBR with the loading of the master record. The PreBoot summary then launches the Windows Manager boot.Manager
2] Windows
The task of loading the Windows Boot Manager is simple. It loads 1 more program - Loader, Windows, known as Winload. It is an exe, located on the new Windows boot partition. this This
While it may seem like a redundant process, the important reason is to help you boot it into a good operating system. If you have multiple operating systems installed on the same computer, be sure to load the correct Winload.exe windows.
3] Operating system loader
The Windows OS Loader instantly loads critical drivers to properly boot the Windows kernel. The kernel eventually takes care of the rest of the time, providing you with an operating system that anyone can run. windows
4] Lant Operating System Kernel
In the final step, the Windows NT kernel puts the system registry in and hives marks additional drivers for reference in the boot_start list. Then control passes to the Forex Trading Broker session process (Smss.exe). The system manager, in turn, initializes the session schema and loads the necessary remaining hardware and software.

Why is my code not working in hive?
I'm assuming you're using HiveServer2, which can be described as the reason why it's not working. You can use pyhs2 to properly access your hive and sample code is as follows: Warning, you can install python-devel.x86_64 cyrus-sasl-devel.x86_64 before installing pyhs2 with pip. Hope this helps you.
