类 TSFInputSplit

java.lang.Object

org.apache.hadoop.mapreduce.InputSplit

org.apache.hadoop.mapred.FileSplit

org.apache.iotdb.hadoop.tsfile.TSFInputSplit

所有已实现的接口:

org.apache.hadoop.io.Writable, org.apache.hadoop.mapred.InputSplit, org.apache.hadoop.mapred.InputSplitWithLocationInfo

public class TSFInputSplit
extends org.apache.hadoop.mapred.FileSplit
implements org.apache.hadoop.io.Writable, org.apache.hadoop.mapred.InputSplit

This is tsfile InputSplit.
Each InputSplit will be processed by individual Mapper task.
