[SPARK-5123][SQL] Expose only one version of the data type APIs (i.e. remove Java-specific APIs) by rxin · Pull Request #3925 · apache/spark

rxin · 2015-01-07T05:49:20Z

Having two versions of the data type APIs (one for Java, one for Scala) requires downstream libraries to also have two versions of the APIs if the library wants to support both Java and Scala. I took a look at the Scala version of the data type APIs - it can actually work out pretty well for Java out of the box.

As part of the PR, I created a sql.types package and moved all type definitions there. I then removed the Java specific data type API along with a lot of the conversion code.

…ve the Java-specific API).

Is this something where we need to make sure to include upgrade details in the release notes?

rxin · 2015-01-07T05:59:57Z

Yes - is there a way to label these things in JIRA?

Make ISO8601GMT this as thread local? or leave a TODO for future improvement.

What do you mean? I don't think I changed this. Simply copied it from a file that was deleted.

chenghao-intel · 2015-01-07T15:26:41Z

That's a very cool idea to make a unified DataType API for jvm-based language. Less code maintenance will be made!

yhuai · 2015-01-07T18:11:46Z

Are scala users expected to use DataTypes?

Sure why not ....
