Arun C Murthy commented on HDFS-4053: ------------------------------------- You'd also have to bump up MR configs to be consistent: I've reopened MAPREDUCE-97. > Increase the default block size > ------------------------------- > > Key: HDFS-4053 > URL: https://issues.apache.org/jira/browse/HDFS-4053 > Project: Hadoop HDFS > Issue Type: Improvement > Reporter: Eli Collins > Assignee: Eli Collins > Attachments: hdfs-4053.txt, hdfs-4053.txt > > > The default HDFS block size ({{dfs.blocksize}}) has been 64mb forever. 128mb > works well in practice on today's hardware configurations, most clusters I > work with use it or higher (eg 256mb).
