Edward Capriolo commented on HIVE-3666:
---------------------------------------

We should really have a .q file here. IT is easy to miss things in generic udfs 
without an end to end test.
                
> implement a udf to keep hive session alive for certain amount of time

> To make testing issues like HIVE-3590 convenient, we can implement a UDF to 
> keep hive session alive for a given time. The patch introduce a new UDF 
> sleep() which does this without introducing any data/load to cluster.
