Hadoop fs lookup for block size?

Question

In Hadoop fs how to lookup the block size for a particular file?

I was primarily interested in a command line, something like:

hadoop fs ... hdfs://fs1.d         


        

Answer 1

For displaying the actual block size of the existing file within HDFS I used:

[pety@master1 ~]$ hdfs dfs -stat %o /tmp/testfile_64
