Hi Mike, I’ve tried hadoop-1.0.3 which doesn’t work as before. Nothing happens after [INFO - org.apache.flume.sink.DefaultSinkFactory.create(DefaultSinkFactory.java:70)] Creating instance of sink: hdfs-sink, type: hdfs I can execute $HADOOP_HOME/bin/hadoop classpath. Don’t know why the HDFS sink is not working.

You must use hadoop 0.20.205, hadoop 1.0.x, hadoop 2.0.x, or CDH3/4 with Flume NG. Regards, Mike On Sat, Sep 29, 2012 at 12:57 AM, Lichen <[email protected]<mailto:[email protected]>> wrote: Hi. I’m using flume 1.2 with hadoop-0.20.2 but unable to use HDFS sink. Flume stuck during creating HDFS sink, which is OK using file-roll or logger sinks. I’ve included $HADOOP_HOME and $HADOOP_HOME/lib in FLUME_CLASSPATH. Is it because my hadoop version not compatible?
