Steve Loughran commented on HADOOP-13998:
-----------------------------------------

Status: review nearly ready. Once In I'm going to create a full diff to see 
what Yetus says...this will list all our style/findbugs issues, so it's a big 
change to review or ignore things.

I'm also thinking of moving all tests from Lambdas to closures, so that a 
branch-2 will be nearly identical to this one. This will make integration 
easier, as well as aid backporting any phase II work.

Mingliang did this internally, which I've got as a starting base. But as 
intelliJ does it itself, it may be simplest to use it for that, leaving only 
any other 8 -> 7 migration issue. Mingliang: what were the other java 7 
migration issues other than us using Lambda expressions in tests.

(FWIW, all the error handling in HADOOP-13786 uses L-exps in production code to 
wrap AWS SDK calls with retry logic, something we need to roll out across the 
FS to handle throttling and other transients. I really want to stay in java 8 
there)
