Subject [jira] Created: (HDFS-1331) dfs -test should work like /bin/test
Date Wed, 04 Aug 2010 21:49:16 GMT
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
            Reporter: Allen Wittenauer
            Priority: Minor
             Fix For: 0.22.0

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 dfs -test -d /nonexist; echo $?
test: File does not exist: /nonexist

$ test -d /nonexist; echo $?

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?
