Subject [jira] [Commented] (HDFS-4053) Increase the default block size
Date Wed, 17 Oct 2012 14:58:04 GMT

    [ https://issues.apache.org/jira/browse/HDFS-4053?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=13477935#comment-13477935
] 

Daryn Sharp commented on HDFS-4053:
-----------------------------------

+1 Assuming test failure is unrelated.  I'd suggest having the default as "128*1024*1024"
(it used to 64*1024*1024) since it's easier to grok.  What would be even better is allow units
such as "M", "G", etc.  I'm sure we have a conversion method lurking somewhere in hadoop.
 Just suggestions.

> 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.
