The Spark indexer uses a Spark or MapReduce ETL batch job to move data from HDFS files into Apache Solr. As part of this process, the indexer uses Morphlines to extract and transform data.

To use the Spark indexer, solr-crunch must be installed on hosts where you want to submit a batch indexing job.

By default, this tool is installed when Cloudera Search is installed using parcels, such as in a Cloudera Manager deployment. If you are using a package installation and this tool does not exist on your system, you can install this tool using the commands described in this topic.

$ sudo yum install solr-crunch

$ sudo apt-get install solr-crunch

$ sudo zypper install solr-crunch
