Installing MapReduce Tools for use with Cloudera Search
Cloudera Search provides the ability to batch index documents using MapReduce jobs. To use the MapReduce tools, solr-mapreduce must be installed on hosts where you want to submit a batch indexing job.
By default, this tool is included with Cloudera Search when you have installed CDH using parcels in a Cloudera Manager deployment. If you are using a package-based installation and this tool does not exist on your system, you can install it using the commands described in this topic.
$ sudo yum install solr-mapreduce
$ sudo apt-get install solr-mapreduce
$ sudo zypper install solr-mapreduce
