Hi All,
I hope this is the right forum for this type of question so my apologies if
not.
I'm looking to write a map reduce program which is giving me the following
compilation error:

not be extending the org.apache.hadoop.mapreduce.Mapper class. From
your snippets it appears that you have it all defined properly though.
A common issue here has also been that people accidentally import the

Thanks

happens.
Thanks.

Thanks for that Harsh.
I just have standard compilation errors now that I'll need to look into.
Thanks for the help, I don't think I would have ever figured that one out.
Cheers
