Deprecation and Obsolete

We strive not to break source compatibility between versions of REEF. Instead, we mark APIs as deprecated or obsolete in one version, and then remove it in the next. When marking something as deprecated:

• Provide an alternative users should switch to.
• Document the alternative, as well as the version of REEF in which the code was deprecated.
• File a JIRA for the removal of the deprecated API in the next version.
• Make sure that all current uses of that API in REEF have either been moved to the new API or been deprecated as well.
