Steve Loughran commented on HADOOP-11858:
-----------------------------------------
thanks for doing this everyone. Alonzo Church came up with the Lambda Calculus
in the 1930s —it's good to be able to use it in Java.
I think a good place to start will actually be tests; I've used closures a lot
there in groovy; ScalaTest's {{eventually(interval, duration, closure)}} call
does the same: lets you declare a closure which is expected to eventually
succeed, time out, or raise a special "this test will never succeed" exception.
It lets you spin efficiently with a fast fail and no need to hard code in long
delays.
