version number larger than 20.
And try to run the sort sample with the following command.
bin/hadoop jar hadoop-*-examples.jar sort [-m <#maps>] [-r <#reduces>]
<in-dir> <out-dir>
HTH.

From hadoop documentation it seems like "TextInputFormat" is a valid option
for input format
I am running a simple sort example using mapreduce.
Here is the command variations I tried, all to vain:
$usr/local/hadoop/bin/hadoop jar /path to hadoop
examples/hadoop-0.18.0-examples.jar sort -inFormat TextInputFormat
-outFormat TextOutputFormat /path to datainput/datain/ /path to data
output/dataout
The sort function does not declare "TextInputFormat" in its import list.
Could that be a problem
?
Could it be a version problem?
Any help is aprpeciated!
