RE: Unable to use HDFS sink
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.

Hi,
Don't use vanilla hadoop 0.20.2 ... you will not get durability.

You must use hadoop 0.20.205, hadoop 1.0.x, hadoop 2.0.x, or CDH3/4 with Flume NG.

Regards,
Mike

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?
