How can we improve Microsoft Azure Data Lake?

Support of Column.Exists feature

I would like to add column to table only if it doesn't exists.

Similar to this is desired :
ALTER TABLE Test2 ADD COLUMN IF NOT EXISTS s string;

OR

!Column.Exists() Then add column.

Currently this is not supported

    Thanks for filing the request. We are looking at adding the IF NOT EXISTS/IF EXISTS options in a future refresh.
