Currently I am using the default block size of 64MB. I would like to change it for my cluster to 256 megabytes since I deal with large files (over 2GB). What is the best way to do this?
What file do I have to make the change on? Does it have to be applied on the namenode or each individual data nodes? What has to get restarted, namenode, datanode, or both? -- --- Get your facts first, then you can distort them as you please.--
