This article introduces the knowledge of "three ways to add custom jar files in Hive". In the operation of actual cases, many people will encounter such a dilemma, so let the editor lead you to learn how to deal with these situations. I hope you can read it carefully and be able to achieve something!

After developing the jar file of hive's udf udaf udtf function, you need to put the jar file into the hive environment before you can use it. You can join in the following three ways:

1. Use the add jar path/test.jar; method to join

The disadvantage of this method is that you have to rejoin every time you start Hive, and exiting hive will fail.

two。 Join by setting the configuration file hive-site.xml of hive

Add configuration to the configuration file

Hive.aux.jars.path

File:///jarpath/all_new1.jar,file:///jarpath/all_new2.jar

Just save it.

This method is much more convenient than the first method. You don't need to start Hive every time you execute the command to join, just a little more complicated to configure.

3. Create the folder auxlib in ${HIVE_HOME}, and then put the custom jar file in that folder.
