Subject: Changing dfs.block.size
Hello,
So I have a question about changing dfs.block.size in
$HADOOP_HOME/conf
Another advice here, is that you can test the right block size with a
seemed enviroment to your production system, before to deploy the real
system, and then, you can avoid these kinds of changes.

Sorry, that's rep factor and not blocksize. I think you need to copy the files.

Hello,
So I have a question about changing dfs.block.size in
$HADOOP_HOME/conf/hdfs-site.xml. I understand that when files are created,
blocksizes can be modified from default. What happens if you modify the
blocksize of an existing HDFS site? Do newly created files get the default
blocksize
