Does that mean libhdfs doesn't support append functionality in 0.19.0, but if I write a Java test program to test hdfs append functionality then it should work? Do I need to apply all the patches given at https://issues.apache.org/jira/browse/HADOOP-1700 to test append functionality using TestFileAppend*.java? Or just having hadoop 0.19.0 should work?
