Uses of InputSplit in org.apache.hadoop.mapred

Subclasses of InputSplit in org.apache.hadoop.mapred
`class` | `FileSplit` A section of an input file.

Uses of InputSplit in org.apache.hadoop.mapreduce

Methods in org.apache.hadoop.mapreduce that return InputSplit
`InputSplit` | `MapContext.getInputSplit()` Get the input split for this map.

Methods in org.apache.hadoop.mapreduce that return types with arguments of type InputSplit
`abstract List<InputSplit>` | `InputFormat.getSplits(JobContext context)` Logically split the set of input files for the job.

Methods in org.apache.hadoop.mapreduce with parameters of type InputSplit
`abstract RecordReader<K,V>` | `InputFormat.createRecordReader(InputSplit split, TaskAttemptContext context)` Create a record reader for a given split.
`abstract void` | `RecordReader.initialize(InputSplit split, TaskAttemptContext context)` Called once at initialization.

Constructors in org.apache.hadoop.mapreduce with parameters of type InputSplit
`MapContext(Configuration conf, TaskAttemptID taskid, RecordReader<KEYIN,VALUEIN> reader, RecordWriter<KEYOUT,VALUEOUT> writer, OutputCommitter committer, StatusReporter reporter, InputSplit split)`
`Mapper.Context(Configuration conf, TaskAttemptID taskid, RecordReader<KEYIN,VALUEIN> reader, RecordWriter<KEYOUT,VALUEOUT> writer, OutputCommitter committer, StatusReporter reporter, InputSplit split)`

Uses of InputSplit in org.apache.hadoop.mapreduce.lib.db

Subclasses of InputSplit in org.apache.hadoop.mapreduce.lib.db
`static class` | `DataDrivenDBInputFormat.DataDrivenDBInputSplit` A InputSplit that spans a set of rows
`static class` | `DBInputFormat.DBInputSplit` A InputSplit that spans a set of rows

Methods in org.apache.hadoop.mapreduce.lib.db that return types with arguments of type InputSplit
`List<InputSplit>` | `DBInputFormat.getSplits(JobContext job)` Logically split the set of input files for the job.
`List<InputSplit>` | `DataDrivenDBInputFormat.getSplits(JobContext job)` Logically split the set of input files for the job.

`List<InputSplit>` | `DBSplitter.split(Configuration conf, ResultSet results, String colName)` Given a ResultSet containing one record (and already advanced to that record) with two columns (a low value, and a high value, both of the same type), determine a set of splits that span the given values.
`List<InputSplit>` | `TextSplitter.split(Configuration conf, ResultSet results, String colName)` This method needs to determine the splits between two user-provided strings.

Methods in org.apache.hadoop.mapreduce.lib.db with parameters of type InputSplit
