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:
$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?
