To create a UDF, we need to extend UDF (org.apache.hadoop.hive.ql.exec.UDF) class and implement evaluate method.
Once UDF is complied and JAR is build, we need to add jar to hive context to create a temporary/permanent function.
import org.apache.hadoop.hive.ql.exec.UDF;
class UDFExample ex...

However, x in the generator expression is not just variable, but can be any pattern. In cases of pattern mismatch the generated element is skipped over, and processing of the list continues with the next element, thus acting like a filter:
[x | Just x <- [Just 1, Nothing, Just 3]] -- [1, 3]
...
With Parallel List Comprehensions language extension,
[(x,y) | x <- xs | y <- ys]
is equivalent to
zip xs ys
Example:
[(x,y) | x <- [1,2,3] | y <- [10,20]]
-- [(1,10),(2,20)]
We consume rest API as a JSON format and then unmarshal it to a POJO. Jackson’s org.codehaus.jackson.map.ObjectMapper “just works” out of the box and we really don’t do anything in most cases. But sometimes we need custom deserializer to fulfill our custom needs and this tutorial will guide you thro...
Tuples support the following build-in functions
