Description

HDFS documentation ( http://hadoop.apache.org/core/docs/current/hdfs_shell.html#du ) mentions that

Exit Code:

Returns 0 on success and -1 on error. 

Current Fs shell behavior is buggy with this agreement.

statepick-lm:Hadoop rphulari$ bin/hadoop fs -ls foo
ls: Cannot access foo: No such file or directory.
statepick-lm:Hadoop rphulari$ echo $?
255
statepick-lm:Hadoop rphulari$ bin/hadoop fs -lsr foo
lsr: Cannot access foo: No such file or directory.
statepick-lm:Hadoop rphulari$ echo $?
255
statepick-lm:Hadoop rphulari$ bin/hadoop fs -du foo
du: Cannot access foo: No such file or directory.
statepick-lm:Hadoop rphulari$ echo $?
255
statepick-lm:Hadoop rphulari$ bin/hadoop fs -dus foo
dus: Cannot access foo: No such file or directory.
statepick-lm:Hadoop rphulari$ echo $?
255
statepick-lm:Hadoop rphulari$ bin/hadoop fs -cp foo f2
cp: File does not exist: foo
statepick-lm:Hadoop rphulari$ echo $?
255
statepick-lm:Hadoop rphulari$ bin/hadoop fs -copyToLocal foo f2
copyToLocal: null
statepick-lm:Hadoop rphulari$ echo $?
255
statepick-lm:Hadoop rphulari$ bin/hadoop fs -copyFromLocal foo f2
copyFromLocal: File foo does not exist.
statepick-lm:Hadoop rphulari$ echo $?
255

In all above cases exit code on error should be -1
