Hi,

Hadoop's append functionality is somewhat in progress and is not stable in
any released versions quite yet. The relevant ticket is
http://issues.apache.org/jira/browse/HADOOP-1700. Note that, while this JIRA
indicates that it is in 0.19.0, it was rolled back in 0.19.1 (
http://issues.apache.org/jira/browse/HADOOP-5224). It is coming back in
0.20, soon to be released, but you may want to investigate other solutions
to your problem in the meantime.
