Review Comment:
Please include the `@Deprecated` annotation it is useful for some purposes.
"Instantiating HiveConf is deprecated" phrase is redundant. IDEs and
compilers will generate automatically similar warnings when calling this method.
"Instatiating...eventually" the whole paragraph concerns deprecation so it
should be associated with the `@deprecated` tag.
Based on [1] and the comments above, I would suggest the following:
```java
/**
* @deprecated This method will become private eventually; Use {@link
#create()} instead.
*/
@Deprecated
public HiveConf() {
```

Review Comment:
If we make those private then we are breaking inheritance which is fine by
me but wanted to mention it just in case.
For sanity reasons I would also attempt to run the precommit tests with all
the constructors private to see if there are any hidden reflection calls or
other exotic usages.
