Subject [jira] Commented: (HADOOP-337) DFS files should be appendable
Date Sun, 02 Jul 2006 00:40:30 GMT
    [ http://issues.apache.org/jira/browse/HADOOP-337?page=comments#action_12418815 ] 

paul sutter commented on HADOOP-337:

If Doug isnt able to talk you out of it, then you must really need it. So give him a chance,
but if its OK with him its probably a good thing to do. We'd love to have it, but my intuition
is flashing *complexity* when I consider it. Especially with multiple appenders.  Of course,
you guys probably have a super elegant approach in mind. 

My last thought: if that "other" elegant distributed replicated block-based filesystem has
this feature, its probably valuable. If it doesnt, then its probably superfluous.

> Actually two related issues
> 1. One should be able to open an existing DFS file, to seek to a position and truncate
the rest, and to append starting at the end (or where trancation happens) .
> 2. One should be able to read the writen data of a DFS file while other is writing/appending
to the file
