---------------------------------------
[~Jaanai] [~brfrn169] I'm seeing the following failure on 4.x-HBase-1.4
Could be a java version thing, this branch is using Java 7. Master is using
Java 8

> Project: Phoenix
> Issue Type: Bug
> Reporter: Gabriel Reid
> Assignee: Toshihiro Suzuki
> Priority: Major
> Labels: argus
> Fix For: 4.15.0

> On an existing table table, executing "ALTER TABLE ADD IF NOT EXISTS
> thisColAlreadyExists varchar, thisColDoesNotExist varchar", then
> nothing will be changed in the table because thisColAlreadyExists
> already exists.
> Omitting the already-existing column from the statement, all new columns
> do get created.
> The general expectation would be that when you use ADD IF NOT EXISTS, all
> non-existent columns will be added, and all existing columns in the
> statement will just be ignored. There is already an integration test
> (AlterTableIT#testAddVarCols) that actually demonstrates the current
> behavior, although this is probably not correct.
> As pointed out in the related mailing list thread [1], ALTER TABLE DROP
> COLUMN likely suffers from the same issue.
