Thanks Jeff !
Following what you have said, I build my hadoop core jar first (command -
ant jar). That created a hadoop-core.jar in the build. Now can you please
tell me how to use this as dependable for the building of examples.jar.
Because if I give ant example , it gives errors like the new
Mattew,
Do you still put your source code in the io package and mapred package ?
If so, rebuild and hadoop core (seems you have done), and then invoke
the command
bin/hadoop -jar hadoop-0.20.2-example.jar sort -libjars
hadoop-core-0.20.2.jar(your new builded jar) other_arguments

Hey Jeff ,
I gave the command :
bin/hadoop jar hadoop-0.20.2-examples.jar sort -libjars
./build/hadoop-0.20.3-dev-core.jar -inFormat
org.apache.hadoop.mapred.MetafileInputFormat -outFormat
org.apache.hadoop.mapred.MetafileOutputFormat -outKey
org.apache.hadoop.io.FpMetaId -outValue
Matthew,
InputFormat will been used in client side, so you should combine the
hadoop-0.20.2.jar and hadoop-example.jar into one single jar

If the jar passed in -libjars is in local filesystem, it is added to client
classpath also.

Hey Guys ! ,
Finally my examples.jar got built :) :) .. It was just a small error - dint
initialize the package for some of the newly written files :P ..
Now i will run the command :
bin/hadoop jar hadoop-0.20.2-examples.jarnew one sort -inFormat

Hi all,
I wrote some new writable files corresponding to my data input. I added
them to /src/org//io/ where all the writables reside. Similarly, I
also wrote input/output format files and a recordreader and added them to
src/mapred/./mapred/ where all related files reside.
I want
Matthew,
You should put your code in the example source folder, and rebuild the
example. And use the new generated hadoop*version*example.jar in the
build folder.
PS: each mapred job needs a jar which contains the classes this job needs

Thanks a lot Jeff !
The problem is that everytime I build (using ant ) there is a build folder
created. But there is no examples.jar created inside that. I wanted to add
some files into io package and mapred package. So I suppose I should put the
files appropriately ( inside io and mapred folder
Do you run ant example ?
