Hi,
I got some question after deploy hadoop-0.21.0 need to help.
There is a new deploy not update, and i execute start-hdfs.sh,
start-mapred.sh, got the message in the log file below:
2010-10-14 16:59:55,354 INFO org.apache.hadoop.ipc.Server: IPC Server
listener on 9000: readAndProcess threw exception java.io.IOException: Unable
to read authentication method. Count of bytes read: 0

And i want to query dfs, got this message:
[had...@hadoopnameslave conf]$ /usr/local/hadoop/bin/hadoop fs -lsr
hdfs://HadoopNameVIP:9000/
10/10/14 16:57:08 INFO security.Groups: Group mapping
impl=org.apache.hadoop.security.ShellBasedUnixGroupsMapping;
cacheTimeout=300000
10/10/14 16:57:09 WARN conf.Configuration: mapred.task.id is deprecated.
Instead, use mapreduce.task.attempt.id
Who can tell me what problem for these? is it the config issue?
Thanks & Regards,
Singo
