I have Hadoop table with IP address, I want to call to my JAR with IP from my table and to get the results from my JAR, Is is possible?

I'm using HUE with Hive/Impala editor and did:

add jar HDFS:///PATH/TO/MY/JAR.JAR

And now I don't know how to use my jar

Any suggestions?

Answer 1

You need to say which class within the JAR to use by defining a function.

CREATE TEMPORARY FUNCTION name AS 'com.example.full.class.name'

Then use name() as a SQL function
