One of the broader issues I want to discuss is the continued use of joda-time http://www.joda.org/joda-time/ * JSR-310 https://jcp.org/en/jsr/detail?id=310 introduced a revamped Date and Time API into the standard Java class libraries under java.time.* * Stephen Colebourne, Mr 'joda-time' himself, was one of the Specification Leads, shepherding this process for many years. http://blog.joda.org/2009/11/why-jsr-310-isn-joda-time_4941.html * JSR-310 was originally targeted for Java 7 but slipped to Java 8. * A backport of JSR-310 is available for Java 6 & 7. This provides equivalent functionality, but under the package name 'org.threeten.bp.*' instead of 'java.time.*' ... as in Java 8. https://github.com/ThreeTen/threetenbp http://www.threeten.org/ My straw-man proposal for evolution of DateTime support is as follows: * The roadmap for pig should include adoption of JSR-310 for Date and Time support * use of joda-time within pig should be deprecated and phased-out * the backport org.threeten.bp.* classes can be used for as long Java 7 (& 6) are supported by pig * When Java 8 becomes the minimum requirement for pig then the package names can be switched to java.time.* ... and the org.threeten.bp dependency can be dropped.
