Subject Re: Can not upload local file to HDFS
Date Sun, 26 Sep 2010 11:29:03 GMT
The problem is every datanode may be listed in the error report. That means
all my datanodes are bad?

One thing I forgot to mention. I can not use start-all.sh and stop-all.sh to
start and stop all dfs and mapred processes on my clusters. But the
jobtracker and namenode web interface still work.

I think I can solve this problem by ssh to every node and kill current
hadoop processes and restart them again. The previous problem will also be
solved( it's my opinion). But I really want to know why the HDFS reports me
previous errors.
