Subject HDFS: how to append
Date Tue, 18 Mar 2008 16:53:29 GMT
The HDFS documentation says it is possible to append to an HDFS file.

In org.apache.hadoop.dfs.DistributedFileSystem class,
there is no method to open an existing file for writing (there are
methods for reading).
Only similar methods are "create" methods which return FSDataOutputStream.
When I look at FSDataOutputStream class, it seems there is no "append"
method, and
all "write" methods overwrite an existing file or return an error if
such a file exists.

Does anybody know how to append to a file in HDFS?
I appreciate your help.
