Assume I have one of the two situations (I have both) 1) I have a directory with several hundred files - of these some fraction need to be passed to the mapper (say the ones ending in ".foo") and the others can be ignored. Assume I am incapable or unwilling to create a directory containing only the files that I need - how do I set up a custom file splitter using Java code to filter my files.
2) Assume I have a collection of files which are not splittable so I will use one file per mapper. Assume that special code is required to read the file and convert it into lines of text and that I have Java code to do that. Same question - how do I install a custom file splitter to decode files in a custom manner? -- Steven M. Lewis PhD Institute for Systems Biology Seattle WA
