Doug Cutting commented on HADOOP-5181:
--------------------------------------
I think the request is for shell access to:
http://hadoop.apache.org/core/docs/current/api/org/apache/hadoop/fs/FileSystem.html#getFileChecksum(org.apache.hadoop.fs.Path)
This seems reasonable to me. It provides access to the checksum that's already
computed & stored.
We could print the checksum as hex. Perhaps we could even print it as a column
with '-lsll' or somesuch.
