Student Name Filter program template | StudentFilter.java | |
Data File | students.csv | HDFS location: /data/students.csv |
Instructor's Jar | lab6.jar | Main Class StudentListFilter |
Instructor's run | filter-run-alex.txt |
Note: please note that instructor's sample run file shows errors in starting some of the map jobs (the run succeeded on the third try after two mappers failed). While this is not the best behavior, a successful run that has some failed map or reduce functions will be accepted, as long as proper output was generated. The failures of the map() and reduce() containers are largely due to the brittleness of our Hadoop cluster.
