[jira] [Commented] (MAPREDUCE-4630) API for setting dfs.block.size

    [ https://issues.apache.org/jira/browse/MAPREDUCE-4630?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=13502797#comment-13502797 ] 

Radim Kolar commented on MAPREDUCE-4630:
----------------------------------------

I look for setting size of output (newly created) block. If there is an API for input block size, why you are against API for setting output block size.
