Subject [jira] [Created] (HDFS-4053) Increase the default block size
Date Mon, 15 Oct 2012 18:56:02 GMT
Eli Collins created HDFS-4053:
---------------------------------

             Summary: 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


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). Let's bump to 128mb in trunk for v3.
