Description

Whenever I try to copy data from local to a cluster, but forget to create the parent directory first, I get a very confusing error message:

$ whoami
fs111

$ hadoop fs -ls  /user
Found 2 items
drwxr-xr-x   - fs111   supergroup          0 2014-08-11 20:17 /user/hive
drwxr-xr-x   - vagrant supergroup          0 2014-08-11 19:15 /user/vagrant

$ hadoop fs -copyFromLocal data data
copyFromLocal: `data': No such file or directory

From the error message, you would say that the local "data" directory is not existing, but that is not the case. What is missing is the "/user/fs111" directory on HDFS. After I created it, the copyFromLocal command works fine.

I believe the error message is confusing and should at least be fixed. What would be even better, if hadoop could restore the old behaviour in 1.x, where copyFromLocal would just create the directories, if they are missing.
