Hi

Are there any plans to provide Java 8 lamdas in Apache Crunch?

Cheers,

I just had a discussion with the people at Apache Flink around Java 8
lambda expression not storing generic type information.

This forces us provide these types manually and I suppose that Crunch
would also benefit from introducing official Java support for
accessing this information?

The flink people had a discussion with the compiler team here at the
beginning of this year [1], which was sort-of rejected (but not
completely). They also provided a patch to eclipse JDT which was
accepted(!) [2].

My thinking is that we may get this through if enough people stand behind?
