public class TsvImporterCustomTestMapper
extends org.apache.hadoop.hbase.mapreduce.TsvImporterMapper

Dummy mapper used for unit tests to verify that the mapper can be injected. This approach would be used if a custom transformation needed to be done after reading the input data before writing it to HFiles.
