org.apache.hadoop.mapreduce.Mapper<WALKey,WALEdit,org.apache.hadoop.io.Text,org.apache.hadoop.io.NullWritable>

Enclosing class:
BulkLoadCollectorJob
public static class BulkLoadCollectorJob.BulkLoadCollectorMapper extends org.apache.hadoop.mapreduce.Mapper<WALKey,WALEdit,org.apache.hadoop.io.Text,org.apache.hadoop.io.NullWritable>
Mapper that extracts relative bulk-load paths from a WAL entry (via BulkLoadProcessor), resolves them to full paths (via BackupFileSystemManager#resolveBulkLoadFullPath(Path, Path)), and emits each full path as the map key (Text). Uses the same table-filtering semantics as other WAL mappers: if no tables are configured, all tables are processed; otherwise only the configured table set is processed. Map output: (Text fullPathString, NullWritable)
