Mukul Kumar Singh commented on HDFS-12636:
------------------------------------------

Thanks for working on this [~ljain],

1) OzoneFSInputStream:21, can you please remove the wildcard here and import 
the specific functions inside "java.io."
2) OzoneFSOutputStream:57, commit key should be done as part of 
outputstream.close(). any reason for the comment there ?
3) ChunkInputStream.java. Please add comments around chunkOffset to explain 
that it is the offset of a chunk inside a key.
4) ChunkGroupInputStream.java. Should we add checkNotClosed() for input stream 
as well ? Also in the implementation in ChunkGroupOutputStream, should key name 
be added as well ?
5) ChunkGroupInputStream.java, 162-164, Can you please add some comments here
7) OzoneFileSystem.java:41, Please remove the wildcards here.
