[jira] [Commented] (HDFS-7336) Unused member DFSInputStream.buffersize

    [ https://issues.apache.org/jira/browse/HDFS-7336?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=14195488#comment-14195488 ] 

Konstantin Shvachko commented on HDFS-7336:
-------------------------------------------

This means that even though we pass buffersize as a parameter into the contructors of DFSInputStream it does not determine the size of the buffer.
I think we can live with the default buffer, so I just propose to remove the member.
Another way is to incorporate buffersize into block reader. Not sure if it helps anything though.
