tJavaMR without tHDFSInput?

Hello, i would like to know if it is possible to implement a job like this:

tJavaMR -> tLogRow

Indeed, is the tHDFSinput block mandatory?
Given that the map code needs an InputRowStruct value, do i have to put the output of the tHDFSinput?
Thank you

Re: tJavaMR without tHDFSInput?

Your output from tJavaMR can be passed to tLogRow for viewing, but that means you've done your computation but not stored the data back to Hadoop. The input (read) and output (write) are interfaces to your Hadoop cluster...
