MapReduceIndexerTool Metadata
The MapReduceIndexerTool generates metadata fields for each input
file when indexing. These fields can be used in morphline commands.
These fields can also be stored in Solr, by adding definitions like the
following to your Solr
schema.xml
file. After the
MapReduce indexing process completes, the fields are searchable through
Solr.<!-- file metadata -->
