[jira] [Created] (ACCUMULO-3369) Recursive Directory Imports
Ariel Valentin created ACCUMULO-3369:
----------------------------------------
Summary: Recursive Directory Imports
Key: ACCUMULO-3369
URL: https://issues.apache.org/jira/browse/ACCUMULO-3369
Project: Accumulo
Issue Type: New Feature
Reporter: Ariel Valentin
Priority: Minor
importDirectory does not recurse through subdirectories to import rifles. It would be nice to add an option that would recurse through subdirectories or accept glob patterns to allow the user to specify multiple directories to import.
Here is a snippet of our email conversation from the mailing list to provide some context:

Ah, ok. Thanks, Mike.
It wouldn't be too bad to ensure that the failures are unique (we could preserve the directory name in the failures dir). I thought that we assign a unique name on the backend (b-XXXXXXX.rf) so I think that's ok now.
What I'm boiling down to: sounds like a reasonable feature to request if you want to file an issue on JIRA, Ariel. :)

Name collision of failures and I think name collision of successes might
cause problems sometimes too. Or maybe that's just with older versions.
Regardless, having to write your own code puts it out of the realm of
easy into at least middling territory - if import directory could
natively handle recursion then it would become easy.

What's the difficulty, Mike? Handling name collision of failures?

Ariel,
There is not an easy way to do this recursively. Your best option is
going to be writing your own wrapper around the import command. If
you're using shell commands, this could be as easy as feeding the
results of 'find . -type d' into a script, or in Java you might
want to
look at DirectoryWalker in Apache Commons as possible solutions.

Hello!
We are running a couple of experiments using
importDirectory and are
curious if there is a simple way to import directories
recursively.
Based on looking at the source code it does not look like it
currently supports that feature:
(https://github.com/apache/__accumulo/blob/__1835c27ca41426ddd570cde14f9612__c45680b917/core/src/main/java/__org/apache/accumulo/core/__client/admin/__TableOperationsImpl.java

Are there plans to add it in the future? Or is there a
simple way to
do this right now?
