Subject [jira] [Commented] (MAPREDUCE-4630) API for setting dfs.block.size
Date Thu, 25 Oct 2012 20:07:12 GMT

    [ https://issues.apache.org/jira/browse/MAPREDUCE-4630?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=13484444#comment-13484444

Vinod Kumar Vavilapalli commented on MAPREDUCE-4630:
----------------------------------------------------

I agree with others here. What is the use-case? Are dfs.block.size and mapreduce.input.fileinputformat.split.minsize
not enough? Seems like you are looking for {{void setMinInputSplitSize(Job job, long size)}}
?
