I need to use ChainMapper for one of my use Case.
I have two mappers, which i need to chain. First mapper takes TextInputFormat, but second mapper has to take different InputFormat, say SequenceFileFormat,
how can i configure my mapreduce job for this use case.?
I have to provide the output of first job as input for the second one, that is where i needed to chain mapper.
I dont think this is possible with multiple inputs.
