Hi hadoop devs, I'm implementing a custom input format and want to understand how to make use of data locality.
AFAIU, only file input format makes use of data locality since the job tracker picks data locality based on the block location defined in the file input split. So, the job tracker code is partly responsible for this. So providing data locality for a custom input format would be to either either extend file input format or modify job tracker code (if that makes sense even). Is my understanding correct? -- Regards, Tharindu blog: http://mackiemathew.com/
