James Taylor commented on PHOENIX-1409:
---------------------------------------

Sure, review board is fine too. Just something where the whitespace diffs don't 
get in the way - also, if you could pair down the changes to the minimum, 
that's always good (i.e. don't make whitespace changes). Another example, I 
noticed one of your tests renames a table from test_table to test_table1. Can 
you keep the original name?

One other question: is the change you made to AlterTableIT necessary:

We should still support setting properties when you do an ADD column.

> Once PHOENIX-1408 is fixed, we should allow HTableDescriptor and 
> HColumnDescriptor properties through the ALTER TABLE <table> SET command. 
> It'd just be a matter of passing these properties through the existing 
> methods, as we support this for CREATE TABLE.
