libhdfs append question

Hi!


I'm using the latest stable 0.19.0 version of hadoop. I'd like to try the new append functionality. Is it available from libhdfs? I didn't find it in hdfs.h interface nor in the hdfs.c implementation.

I saw the hdfsOpenFile's new flag O_APPEND in: HADOOP-4494
(http://mail-archives.apache.org/mod_mbox/hadoop-core-dev/200810.mbox/%3C270645717.1224722204314.JavaMail.jira@brutus%3E),
but I still don't find it in the latest release.

Is it available as a patch, or maybe only available in the svn repository?

Could you please give me some pointers how to use the append functionality from libhdfs?
Thank you in advance!

Cheers,
Tamas

Tamas,

There is a patch attached to the issue, which you should be able to 
apply to get O_APPEND .
