Hive ODBC Connector 2.6.1 for Cloudera Enterprise. Easily Build BI Applications with Open Source, Interactive SQL. The Cloudera ODBC Driver for Hive enables your enterprise users to access Hadoop data through Business Intelligence (BI) applications with ODBC support. The default string column length for Hortonworks Hadoop Hive is 255 characters. For more information about Hortonworks Hive ODBC driver configuration options, and specifically about DefaultStringColumnLength, see the Hive ODBC Driver User Guide (Link opens in a new window) from Hortonworks.

As with most BI tools, QlikView can use Apache Hive (via ODBC connection) as the SQL access to data in Hadoop. Here we are going to talk about qlikview how to connect Hortonworks Hive via ODBC.

1.Install the 64 bits Hortonworks Hive ODBC Driver, you can download ODBC Driver from here. 2.Configure ODBC connection Open Control Panel, search for ODBC and open ODBC Data Source Administrator, in System DSN tab click Add, configure the data source as below, click OK. I'm trying to log into Hortonworks Hadoop Hive from Tableau Desktop and looks like i don't have the right drivers installed since the 'sign in' button is greyed out. I was trying to download the drivers for ODBC from hortonworks and it redirects to Cloudera. I cannot for the life of me figure out where the archive downloads.
Prerequisites
1.Those are versions of each component we installed in Hortonworks
Hue | HDP | Hadoop | Hive-Hcatalog | Ambari | HBase | Hortonworks ODBC Driver |
2.3.1 | 2.1.2 | 2.4.0 | 0.13.0 | 1.5.1 | 0.98.0 | 1.4.8.1008 |
2.We need to make sure HiveServer2 started. https://burncart.weebly.com/blog/mongodb-34-download-for-mac.
3.Here are the configuration for hive server2. Please note the authentication is NONE.
Key | Value |
hive.server2.authentication | NONE |
hive.server2.enable.doAs | FALSE |
hive.server2.long.polling.timeout | 5000 |
hive.server2.max.start.attempts | 30 |
hive.server2.table.type.mapping | CLASSIC |
hive.server2.tez.default.queues | default |
hive.server2.tez.initialize.default.sessions | FALSE |
hive.server2.tez.sessions.per.default.queue | 1 |
hive.server2.thrift.http.max.worker.threads | 500 |
hive.server2.thrift.http.min.worker.threads | 5 |
hive.server2.thrift.http.path | cliservice |
hive.server2.thrift.http.port | 10001 |
hive.server2.thrift.max.worker.threads | 500 |
hive.server2.thrift.min.worker.threads | 5 |
hive.server2.thrift.port | 10000 |
Configure ODBC connection
1.Install the 64 bits Hortonworks Hive ODBC Driver, you can download ODBC Driver from here.
2.Configure ODBC connection
Open Control Panel, search for ODBC and open ODBC Data Source Administrator, in System DSN tab click Add, configure the data source as below, click OK.

3.Click Test
Connect to ODBC data source
1.Open QlikView 11 client, (close the Wizard if it appears), click File -> Edit Script, in Data tab choose ODBC as Database and click Connect, select the Data Source you created in previous step and type the User ID/Password:
2.The ODBC connection code are generated automatically in scripts
3.Click File -> Reload to load data

Tips for Hive ODBC Connection Issue
The ODBC connection might failed for some reasons. Here are some tips for trouble shooting.
1.Make sure hive server2 started.
https://burncart.weebly.com/download-maxwell-cd-label-template-mac.html. a) You can verify that port 10000 is in use once you start hiveserver2.
sudo netstat -tulpn | grep 10000

b) HiveServer2 supports a new command shell Beeline that works with HiveServer2. It’s a JDBC client that is based on the SQLLine CLI.
bin/beeline
!connect jdbc:hive2://HadoopLab2:10000
2.Make sure authentication mechanism of hive server2 is proper. You should select mechanism base on hive configuration file. Here we set ‘NONE’ in configuration file. But when mechanism ‘No Authentication’ is selected, the test results always are timeout, and when ‘username’ selected, any value entered in username input box, test result is successfully. It’s weird.
