I am trying to connect to hive from Tableau 8.1. I instaleld the HDP Hive driver and when I connect from the ODBC adminsitrator..it works fine…
——————————————-
Driver Version: V1.4.5.1005
Running connectivity tests…
Attempting connection
Connection established
Disconnecting from server
TESTS COMPLETED SUCCESSFULLY!
——————————————-

but when I select the Hortonworks Hadoop Hive Connection in Tableau, and type in the server’s IP address in step 1 (leaving the port untouched), and click connect in step 2 and receive the below message:

The drivers necessary to connect to this database server are not properly installed. Visit http://www.tableausoftware.com/drivers to download driver setup files.
[Microsoft][ODBC Driver Manager] Data source name not found and no default driver specified

Unable to connect to the server “192.168.24.128?. Check that the server is running and that you have access privileges to the requested database.
Unable to connect to the server. Check that the server is running and that you have access privileges to the requested database.

No problems connecting via Excel 2013.

Can someone please help

Installing Flume

Hi everyone,

First of all, I am totally new to Hadoop, Linux and Horton Works so forgive me if I ask some stupid questions!

Basically I have installed the HW Sandbox successfully and would now like to install Flume to load in some Twitter data (as in Tutorial 12). However, when I follow the instructions in Tutorial 12 the installation does not work – I receive a PYCURL ERROR 6 message – can’t find a valid base URL for repo: base when I execute the YUM install command.

Also, even when I ping google.com or any other site I receive an ‘unknown host’ error also so I’m guessing I don’t have the sandbox shell configured to access the internet. Any help you can give me to resolve would be great.

Thanks!

Hi All,
I am evaluating Ambari for managing my cluster. I have the following questions
1. Is rpm the only way to install Ambari? Is there a way to manually install using tarballs – something along the lines of http://goo.gl/DTIsRL?
2. How to make sure that Ambari doesnt become a single point of failure?
3. Is it possible to configure ambari to point to an external database? If so, are there instructions to configure the database for ambari?

Thanks,
Karthick

Local repository won't work (The requested URL returned error: 403 Forbidden)

Hello,

I am trying to configure ambari without access to the internet, I have successfully installed and configure a ftp server to work as a repository mirror.
I’ve looked around and after allot of configuration / re-configuration I’m still not able to get over the “403″ error.
The following steps were followed:
1. installed vsftpd
2. created a repo in /var/ftp/pub/hdp/HDP-UTILS-1.1.0.17
3. ran createrepo in the ../HDP-UTILS-1.1.0.17/repos/centos6/repodata/
4. chmoded -R to 775
5. added a new repo to /etc/yum.repos.d/hdp.conf (triple checked the baseurl, it is correct, copy pasting it in a “curl baseurl” will work)
6. disabled iptables, selinux
7. able to curl,wget,navigate in a browser to ftp://fqdn-hostname/pub/hdp/HDP-UTILS-1.1.0.17/repos/centos6/repodata/repomd.xml
8. ran yum clean all
9. yum list will give me this error “ftp://fqdn-hostname/pub/hdp/HDP-UTILS-1.1.0.17/repos/centos6/repodata/repomd.xml: [Errno 14] PYCURL ERROR 22 – “The requested URL returned error: 403 Forbidden”

I’m trying to find out why I still get the 403 when running the yum install command. Do you have any sugestions?

PS. I actually went in python and using the pycurl module, called the URL and it gets an answer from the baseurl used in yum.repos.d.

Thanks!
