Permanently added UDF doesn't work with ODBC connection

[#1]

I'm using the Hortonworks Hive ODBC driver in my application.

I did: CREATE FUNCTION MyFunc as 'com.my.udf.class' USING JAR 'hdfs:///user/location/to/my.jar';

That worked. Ehen I close my HiveCLI session and open it back up, I can immediately run SELECT myfunc(data) FROM tbl; and it loads the class and functions correctly. However it doesn't work inside of HUE or in my ODBC connection within my app.

[#2]

Can you give details of how it doesn't work? Does it not find the function, or find the function and fail to execute it properly?

[#3]

Sorry, yeah using HUE or through my ODBC application it says it can't find the function. I'm logging into the application in HUE with the same username I am with through the HiveCLI.

To be specific:

Error occurred executing hive query: Error while compiling statement: FAILED: SemanticException [Error 10011]: Line 1:155 Invalid function

[#4 · Accepted solution]

Both Hue /ODBC make use of HiveServer2. You might want to check the HiveServer2 logs to see if there are any errors when running these queries. Is the HDFS location of your JAR accessible to the "hive" user (or whatever user is running HiveServer2)?

Logging in with the same username with Hue as I am with HiveCLI. Getting this error

Error occurred executing hive query: Error while compiling statement: FAILED: SemanticException [Error 10011]: Line 1:155 Invalid function

What database was the function created under (permanent functions are qualified with a database name). If you did not specify the DB name when you created it, it would have automatically used the current DB. Do you see the fully qualified function name when you run SHOW FUNCTIONS?

[#7]

It was not created with a specific database. If I run SHOW FUNCTION within the HiveCLI it shows up as default.<myfunction>. If I run SHOW FUNCTION in Hue, the function does NOT show up even though I'm using the "default" database. Is there a way I can make it not be under "default." and just "<function>"? Hue/App using ODBC has no problem using those functions (e.g. count()).

If I add the jar file in Hue (one the left sidebar) and the function/class information it all works.

[#8]

There was supposed to be a RELOAD FUNCTIONS command to refresh the function list if the function was created in a different environment from the current one like what you have done here. However it looks like this command was not working properly in HDP 2.3. It was fixed in HIVE-13043.

The workaround for HDP 2.3 would be to restart HiveServer2, or to create the function in Hue/ODBC rather than in a separate HiveCLI.

I can't seem to reply to your last comment but that was exactly the problem.

@Kevin Vasko @jdere Can you check if hive.server2.enable.doAs is set to True ?

Which version of Hive you are using ?
