Xiaoyu Yao commented on HDFS-11853:
-----------------------------------

Thanks [~vagarychen] for the patch. The patch looks great to me overall. Here 
are a few minor issues. 

DistributedStorageHandler.java
Line 345: why we are using args.getKeyName() not the containerKey to read from 
ChunkInputStream? I remember we use containerKey (/Volume/Bucket/Key) for write 
with ChunkOutputStream.

KSMKeyMetrics.java
Line 170: typo: "getNumKeyAllocateFailes" -> "getNumKeyAllocateFails"

TestKeySpaceManager.java
Line 325-331. you can use the ExpectedException from junit to verify the 
negative case.
