问题
I'm trying to get LibreOffice's Base v5.1.4.2, running on Ubuntu v16.04 to connect to a Hive v1.2.1 database via JDBC. I added the following jars, downloaded from Maven Central, to LibreOffice's classpath ('Tools -> LibreOffice -> Advanced -> Class Path'):
hive-common-1.2.1.jar
hive-jdbc-1.2.1.jar
hive-metastore-1.2.1.jar
hive-service-1.2.1.jar
hadoop-common-2.6.2.jar
httpclient-4.4.jar
httpcore-4.4.jar
libthrift-0.9.2.jar
commons-logging-1.1.3.jar
slf4j-api-1.7.5.jar
I then restarted LibreOffice, opened Base, selected 'Connect to an existing database' -> 'JDBC' and set the following properties:
I entered the credentials and clicked the 'Test Connection' button, which returned a "the connection was established successfully" message. Great!
In the LibreOffice Base UI, the options under the 'Tables' panel were grayed out. The options in the queries tab were not, so I tried to connect to Hive.
The 'Use Wizard to Create Query' option prompts for a password and then returns "The field names from 'airline.on_time_performance' could not be retrieved."
The JDBC connection is able to connect to Hive and list the tables, though it seems to have problems retrieving the columns. When I try to execute a simple select statement, the 'Create Query in SQL View' option returns a somewhat cryptic "Method not supported" message:
The error message is a bit vague. I suspect that I may be missing a dependency since I am able to connect to Hive from Java using JDBC.
I'm curious to know if anyone in the community has LibreOffice Base working with Hive. If so, what am I missing?
回答1:
The Apache JDBC driver reports "Method not supported" for most features, just because the Apache committers did not bother to handle the list of simple yes/no API calls. Duh.
If you want to see by yourself, just download DBVisualizer Free, configure the Apache Hive driver, open a connection, and check the Database Info tab.
Now, DBVis is quite permissive with lame drivers, but it seems that LibreOffice is not.
You can try the Cloudera Hive JDBC driver as an alternative. You just have to "register" -- i.e. leave your e-mail address -- to access the download URL; it's simpler to deploy than the Apache thing (based on the Simba SDK, all Hive-specific JARs are bundled) and it works with about any BI tool. So hopefully it works with LibreThing too.
Disclaimer: I wish the Apache distro had a proper JDBC driver, and anyone could use it instead of relying of "free" commercial software. But for now it's just a wish.
