Subject [jira] Commented: (HADOOP-337) DFS files should be appendable
Date Sat, 01 Jul 2006 01:43:30 GMT
    [ http://issues.apache.org/jira/browse/HADOOP-337?page=comments#action_12418752 ] 

Doug Cutting commented on HADOOP-337:
-------------------------------------

Can you describe more about the application that requires this feature?  I wonder if there
might be a reasonable workaround.  Previously I proposed using a directory of files instead
of a single file for a related issue.

> 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
