Example apps get stuck
Hi,
I am doing some work on distributed computing, and I'm really glad to
have found a java implementation of mapreduce, since it fits my needs
perfectly, but I have tried unsuccessfully for several days to get hadoop up
and running. Currently, I'm able to run the start-all.sh, so all the daemons
are successfully set up (all on localhost). Then when I try and run the
example WordCount application,
[/hadoop]$ bin/hadoop org.apache.hadoop.examples.WordCount indir outdir
060224 235354 parsing file:/C:/cygwin/hadoop/conf/hadoop-default.xml
060224 235354 parsing file:/C:/cygwin/hadoop/conf/mapred-default.xml
060224 235354 parsing file:/C:/cygwin/hadoop/conf/hadoop-site.xml
060224 235354 Client connection to 127.0.0.1:9004: starting
060224 235354 Client connection to 127.0.0.1:9002: starting

060224 235354 Running job: job_o2zoub
060224 235355 map 0% reduce 0%
And it gets stuck there. I'm running this with cygwin on window, with
conf/slaves with a single line 'localhost'. indir has two text files, and
outdir is empty.
Any idea what I'm doing wrong? Help would be greatly appreciated. Thanks
