> Often, we need to create new indexes on master tables way after the data exists on the
master tables.  It would be good to have a simple MR job given by the phoenix code that users
can call to have indexes in sync with the master table. 
> Users can invoke the MR job using the following command 
> hadoop jar org.apache.phoenix.mapreduce.Index -st MASTER_TABLE -tt INDEX_TABLE -columns
> Is this ideal?
