I’m running hive in thrift server mode. I have a UDF in a jar

  • 0

I’m running hive in thrift server mode. I have a UDF in a jar file that I’m trying to use by running

add jar <path to jar>
create temporary function func_name as 'com.test.udf.UDF_CLASS'

However, when I run the create temporary function command I get an error

Query returned non-zero code: 9, cause: FAILED: Execution Error,
return code 1 from org.apache.hadoop.hive.ql.exec.FunctionTask

I’ve checked that the name & path of the jar and that the user running the hive server has all the correct permissions to access the jar. What is weird is if I run hive in CLI mode and run the exact same commands, then everything works. Any ideas on why hive CLI may be behaving differently from the hive thrift server?

    Fixed the problem using the following steps:

    1) Place each UDF jar in /usr/lib/hive/auxlib

    2) Specify the path to each jar in hive-site.xml for the hive.aux.jars.path property (ex: file:///usr/lib/hive/auxlib/jar1.jar,file:///usr/lib/hive/auxlib/jar2.jar)

    3) Create a script to make a thrift request to the hive server to run create temporary function func_name as ‘com.test.udf.ClassName’ for each UDF after the hive server is started

    Edit: For Hive 0.9 no matter what I did, Hiveserver couldn’t find jars in the auxlib directory. To get this to work on Hiveserver 0.9 I had to just dump the jar in the directory specified by Hive’s classpath.
