org.apache.hadoop.hive.accumulo.mr

Class HiveAccumuloSplit

java.lang.Object

org.apache.hadoop.mapreduce.InputSplit

org.apache.hadoop.mapred.FileSplit

org.apache.hadoop.hive.accumulo.mr.HiveAccumuloSplit

All Implemented Interfaces:

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

public class HiveAccumuloSplit
extends org.apache.hadoop.mapred.FileSplit
implements org.apache.hadoop.mapred.InputSplit

Wraps RangeInputSplit into a FileSplit so Hadoop won't complain when it tries to make its own Path.

If the RangeInputSplit is used directly, it will hit a branch of code in HiveInputFormat.HiveInputSplit which generates an invalid Path. Wrap it ourselves so that it doesn't error
