Suresh Srinivas commented on HDFS-2453:
---------------------------------------

Comments:
# ByteRangeInputStream.java
#* cast to HttpUrlConnection unncessary in #openConnection(final long...)
#* I am bit confused by the methods. #openConnection() is public. It could be 
called when offsetUrl is null. Should #openConnection() be private? and 
#openConnection(final long ...) be public? 
#* Why in #removeOffsetParam() check for both startsWith and contains. Just 
contains is sufficient to move to the next for loop.
# DatanodeWebHdfsMethods#put(), #post(),#get() should not throw 
URISyntaxException
# WebHdfsFileSystem#ugi hides HftpFileSystem#ugi
# MockHttpUrlConnection#responseCode hides HttpUrlConnection#responseCode
