    Description

      DFSClient currently does not enforce that dfs.block.size is a multiple io.bytes.per.checksum. This not really problem currently but can future upgrades like HADOOP-1134 (see one of the comments http://issues.apache.org/jira/browse/HADOOP-1134#action_12488542 there).

      I propose DFSClient should fail loudly and ask the user politely to change the config to meet this conidtion. Of course we will change the documentation for dfs.block.size also.
