Description

The immediate motivation for this was the ticket HIVE-4485 . Beeline prints NULLs as empty strings. This is not a desirable behavior. But if we fix it, it breaks backward compatibility.
But we should not be burdening all users with mistakes of the past, specially the users who are new to hive. As hadoop and hive adoption increases proportion of 'new' users will continue to increase.

We need a way to let users choose between backward compatible behavior and more sensible behavior. How this is implemented can be discussed in a separate jira.

The purpose of this Task jira is just to collect list of config flags whose current default is not the desirable one.
