Subject [jira] Commented: (HADOOP-5826) distcp could have an option to preserve the full source path
Date Thu, 18 Jun 2009 21:22:12 GMT

    [ https://issues.apache.org/jira/browse/HADOOP-5826?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=12721500#action_12721500
] 

Rodrigo Schmidt commented on HADOOP-5826:
-----------------------------------------

There are already two tests and two error messages that cover this case:

- If basedir is not a prefix of the source (which will probably happen if it doesn't exist),
it'll print: "Basedir [dir] is not a prefix of source path [src]"

- If basedir is a prefix but is not a directory, it'll print: "Basedir [dir] is not a directory"

Adding a new error message for the case where the directory doesn't exist looks like a redundant
test given the first error case.

> It would be helpful to have an option that preserves the full source path when copying
files from one location to another. This is specially important when archiving/moving files
from one cluster to another one.
