Subject namenode memory test
Date Wed, 24 Apr 2013 02:26:27 GMT
Hi, I would like to know  how much memory our data take on the name-node per block, file and
directory. 
For example, the metadata size of a file.
When I store some files in HDFS,how can I get the memory size take on the name-node?
Is there some tools or commands to test the memory size take on the name-node?


I'm looking forward to your reply! Thanks!
