> Implement a new Impala built-in function named prettyprint_duration. This
> function will take in two inputs -- a duration (all integer/floating
> point/decimal types) and a unit (nanoseconds, microseconds, milliseconds, and
> seconds) and output a prettyprinted, human readable string.
> For example:
> {noformat}
> select prettyprint_duration(2147483647, 'nanoseconds,);
> output: 2s147ms
> {noformat}
