Andrew Wang commented on HDFS-8191:
-----------------------------------

Couple notes:

* Rather than adding another argument to addSomeBlocks, let's keep the one-arg 
form of addSomeBlocks and have it default negativeBlocks to false. Have a 
two-arg form just for testWriteRead.

I'm not very happy with this test in general. Not exactly related to this 
change, but if you don't mind let's do a few small cleanups:

* Make addSomeBlocks and blockIdToLen static
* testWriteRead's "read" function, let's break it out into a new static 
function "readSomeBlocks" and put it by addSomeBlocks. The logic is heavily 
interlinked.
