----------------------------------

Jo Desmet, how did you verify that dfs -put failed?
{quote}
Unix, simply using {{$?}}. I did confirm that I was able to detect other error
conditions, like source file non-existing. Additionally when the untrapped
exception occurred, I also verified that the file was either missing or
incomplete at the target location. [~linyiqun], checking checksum seems to be
extreme if an exception is somehow already generated?

> Key: HDFS-10400
> URL: https://issues.apache.org/jira/browse/HDFS-10400
> Project: Hadoop HDFS
> Issue Type: Bug
> Reporter: Jo Desmet
> Assignee: Yiqun Lin
> Attachments: HDFS-10400.001.patch, HDFS-10400.002.patch
>
>
> On a filesystem that is about to fill up, execute "hdfs dfs -put" for a file
> that is big enough to go over the limit. As a result, the command fails with
> an exception, however the command terminates normally (exit code 0).
> Expectation is that any detectable failure generates an exit code different
> than zero.
> Documentation on
> https://hadoop.apache.org/docs/r1.2.1/file_system_shell.html#put states:
> Exit Code:
> Returns 0 on success and -1 on error.
> following is the exception generated:
