I never knew you could do that with templates and exceptions! 1. can you put into org.apache.hadoop.fs.impl where the other internal-for-fs-only lambda stuff is going. 1. be advised that for backports to branch 2 we will have to make things compile on Java 8. Mostly this is just using the IDE to convert things to callables. Doesn't mean they shouldn't be used, only that once you get sufficiently advanced things become unbackportable.
