java.lang.Objectorg.apache.hadoop.hive.ql.io.CombineHiveInputFormat.CombineHiveInputSplit
public static class CombineHiveInputFormat.CombineHiveInputSplit
CombineHiveInputSplit encapsulates an InputSplit with its corresponding inputFormatClassName. A CombineHiveInputSplit comprises of multiple chunks from different files. Since, they belong to a single directory, there is a single inputformat for all the chunks.
