Hi all, I'm a rookie to HDFS. Here is just a quick question, suppose I have a big file stored in HDFS, is there any way to generate a file containing all information about blocks belong to this file? For example list of records with format of "block_id, length, offset, hosts[], local/path/to/this/block"?
The purpose is to enable programs to only access blocks on the same node, to utilize block locality. I can retrieve most information using getFileBlockLocations() but I didn't find how to gather information about the local path. Thanks, Yuduo
