Hi,

A user is having problems when performing wordcount operation. Here it is
his report:

"The error happens when we try to make a second wordcount. The first works
fine, but the second occasionally brings us this error.
To do the wordcount we connect to the virtual machine via ssh, as shown in
the documentation.
(hadoop jar /usr/lib/hadoop-0.20/hadoop-examples.jar wordcount /user/'+
ssh.user + inputDir ' /user/' ssh.user + outputDir)

we believe that the error is that the ssh connection does not close
properly, but we are not sure that we find it hard to reproduce the error:

"


Thanks in advance,
Xavier Carol.
