FAQ
Firstly, I think your hadoop version is a bit too old, maybe you can try
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.

I am running basic hadoop examples on amazon emr and I am stuck at a very
simple place. I am apparently not passing the right "classname" for
inputFormat

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!
