> One requirement for HIVE-787 is that users would like to run a command whenever a new partition of a Hive table gets created.
> There are several ways to achieve this functionality:
> A. Probe and wait: We can have the scripts running in a loop checking if a new partition is created.
>   Pros: easy to write, easy to control
>   Cons: will introduce another delay based on the probing interval.
> B. Triggered: The command is registered inside the hive metastore. Whenever a partition gets created, we run the registered command. 
> Several questions around option B are:
> 1. whether to support registration of HiveQL or shell command;
> 2. which machine/environment to run the command;
> 3. what to do if the registered command failed.
