Subject [jira] [Commented] (HADOOP-8545) Filesystem Implementation for OpenStack Swift
Date Thu, 31 Jan 2013 14:49:13 GMT

    [ https://issues.apache.org/jira/browse/HADOOP-8545?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=13567682#comment-13567682
] 

Tom White commented on HADOOP-8545:
-----------------------------------

I wonder whether this would be better hosted outside Hadoop Common, since it's an optional
feature, and won't get tested against Swift during routine Hadoop development. We recommended
this course of action for KFS when it became QFS recently:

http://mail-archives.apache.org/mod_mbox/hadoop-common-dev/201210.mbox/%3CCC946699.1C97B%25thilee@quantcast.com%3E

It's a non-trivial amount of code: it adds over 35 Java classes in 9 packages to core. Does
it add any new dependencies? I tried compiling and it complained about not being able to find
org.apache.http.HttpHeaders.

It looks like the native implementation supports large files now. If so, then the block store
implementation is redundant and can be removed.
