FileSplit

org.apache.hadoop.hive.ql.io.SymlinkTextInputFormat.SymlinkTextInputSplit

Enclosing class:

SymlinkTextInputFormat

public static class SymlinkTextInputFormat.SymlinkTextInputSplit
extends FileSplit

This input split wraps the FileSplit generated from TextInputFormat.getSplits(), while setting the original link file path as job input path. This is needed because MapOperator relies on the job input path to lookup correct child operators. The target data file is encapsulated in the wrapped FileSplit.
