Subject [jira] [Commented] (HADOOP-8761) Help for FsShell's Stat incorrectly mentions "file size in blocks" (should be bytes)
Date Tue, 04 Sep 2012 17:43:07 GMT

    [ https://issues.apache.org/jira/browse/HADOOP-8761?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=13447840#comment-13447840
] 

Andy Isaacson commented on HADOOP-8761:
---------------------------------------

bq. I think the correct behavior should be to match the usage. The unix stat uses %b for blocks,
and %s for size in bytes.

I agree that adding %s for size in bytes is a good idea, but changing the semantics of %b
is an incompatible change, which seems risky.  OTOH, I think it would be potentially very
useful to expose "number of blocks in this file".

Tangentially, the documentation also fails to describe %F.

> Trivial patch attached corrects the usage information.  Stat.java calls FileStatus.getLen(),
which is most definitely the file size in bytes.
