I looked into the namenode log and found this message:
2015-01-22 22:18:39,441 WARN org.apache.hadoop.ipc.Server: Incorrect header or
version mismatch from 10.33.140.233:53776 got version 9 expected version 4
What should I do to fix this?
Thanks.

The hdfs release should be hadoop 1.0.4.

What hdfs release are you using ?
Can you check namenode log around time of error below to see if there is some
clue ?
Cheers

Hi,
I used the following fragment of a scala program to save data to hdfs:
contextAwareEvents
.map(e => (new AvroKey(e), null))
.saveAsNewAPIHadoopFile("hdfs://" + masterHostname + ":9000/ETL/output/"
+ dateDir,
classOf[AvroKey[GenericRecord]],
classOf[NullWritable],
classOf[AvroKeyOutputFormat[GenericRecord]],
job.getConfiguration)
But it failed with the following error messages. Is there any people who
can help? Thanks.
