Your custom implementation of any interface from hadoop-core should be
archived together with the application (i.e. in the same jar).
Andt he jar will be added to CLASSPATH of the task runner, then your
"customwritable.java" could be found.

Hi,
I am new to hadoop. For my map/reduce task I want to write my on custom
writable class. Could anyone please let me know where exactly to place the
customwritable.java file?
I found that in {hadoop-home}
/hadoop-{version}/src/java/org/apache/hadoop/io/ all type of writable
class
files are there.
Then in the main task, we just include "import
org.apache.hadoop.io.{X}Writable;" But this is not working for me.
Basically
at the time of compilation compiler doesn't find my customwritable class
which i have placed in the mentioned folder.
plz help me in this endevor.
Thanks
