I am testing the word count demo, e.g.
bin/hadoop jar hadoop-0.8.0-examples.jar wordcount -m 40 -r
12 /in /out
This example work before, but I don't know why suddenly it
is not working, i.e.
06/12/03 19:14:05 ERROR mapred.JobClient: Input directory
/in in local
is invalid.
java.io.IOException: Input directory /in in local is
invalid.
and from the namenode log, i found:
2006-12-03 19:12:37,460 WARN
org.apache.hadoop.dfs.StateChange: DIR*
FSDirectory.unprotectedDelete: failed to remove
/hadoop/mapred/.system.crc because it does not exist
2006-12-03 19:12:37,470 WARN
org.apache.hadoop.dfs.StateChange: DIR*
FSDirectory.unprotectedDelete: failed to remove
/hadoop/mapred/system
because it does not exist
are they related?
remark: I can still put files into the DFS using -put
thanks for any comments
