--------------------------------
Attachment: hdfs1331-4.txt
> dfs -test should work like /bin/test
> ------------------------------------
>
> Key: HDFS-1331
> URL: https://issues.apache.org/jira/browse/HDFS-1331
> Project: Hadoop HDFS
> Issue Type: Bug
> Components: tools
> Affects Versions: 0.20.2, 3.0.0, 2.0.2-alpha
> Reporter: Allen Wittenauer
> Assignee: Andy Isaacson
> Priority: Minor
> Attachments: hdfs1331-2.txt, hdfs1331-3.txt, hdfs1331-4.txt,
> hdfs1331.txt, hdfs1331-with-hadoop8994.txt

> hadoop dfs -test doesn't act like its shell equivalent, making it difficult
> to actually use if you are used to the real test command:
> hadoop:
> $hadoop dfs -test -d /nonexist; echo $?
> test: File does not exist: /nonexist
> 255
> shell:
> $ test -d /nonexist; echo $?
> 1
> a) Why is it spitting out a message? Even so, why is it saying file instead
> of directory when I used -d?
> b) Why is the return code 255? I realize this is documented as '0' if true.
> But docs basically say the value is undefined if it isn't.
> c) where is -f?
> d) Why is empty -z instead of -s ? Was it a misunderstanding of the man page?
