steveloughran commented on issue #716: HADOOP-16205 Backporting ABFS driver 
from trunk to branch 2.0
URL: https://github.com/apache/hadoop/pull/716#issuecomment-482759642
 
 
   -1 as is
   
   I'm not worried about the abfs changes itself: that's what the testing is 
for. I've been more reviewing the changes outside the hadoop-azure module as 
that's where the risk of side effects is hightest. 
   
   * There's some stuff on Erasure Coding (see Ls) which seems spurious and is 
mostly commented out anyway.
   * `AbstractContractAppendTest` needs HADOOP-15744 applied to it
   * The move away from `intercept()` in the tests means that they aren't 
actually stressing things (e.g AbstractContractConcatTest)
   
   I can see why you've tried to move off intercept(), with java 8 as the 
target language, but the method can be used with Callable<> operations so does 
work with java 7. In fact, we started adding it for java 7 
[HADOOP-13716](https://issues.apache.org/jira/browse/HADOOP-13716).
   If you move back to the intercept calls, you can use intellij to convert the 
l-expressions to Callables at the click of a mouse (one caveat: needs to think 
the language is java 8 still, so you have to do it before changing the language 
version to java 7)
