Also note that the block size in recent releases is actually called
"dfs.blocksize" as opposed to "dfs.block.size", and that you can set it per
job as well. In that scenario, just pass it as an argument to your job (e.g.
Hadoop bla -D dfs.blocksize= 134217728)

Change the dfs.block.size in hdfs-site.xml to be the value you would like if
you want to have all new files have a different block size.

I see the default block size for HDFS is 64 MB, is this a value that can be
changed easily?
