Packaging and Deploying the Coprocessor JAR File

For the region servers to perform searches, you must package the search logic in a JAR file. You can then deploy the generated JAR file to a directory in HDFS so that the region servers can access the search logic.

To package the search logic in a JAR file, run the

run_deployment.sh

script located in the following directory:

/usr/local/mdmbdrm-<Version Number>

Use the following command to run the

run_deployment.sh

command:

run_deployment.sh

--config=configuration_file_name

--installbin=install_bin_directory

--coprocessor

--id=identifier_for_the_JAR_file

[--rule=matching_rules_file_name]

The following table describes the options and arguments that you must specify to run the

run_deployment.sh

script:

Option	Argument	Description
--config	configuration_file_name	Absolute path and file name of the configuration file that you create.
--installbin	install_bin_directory	Absolute path to the bin directory of the Relate 360 installation.
--id	identifier_for_the_JAR_file	Unique identifier for the coprocessor JAR file. The name format of the generated JAR file is db-hbase-coprocessor<id> . For example, if id=Deploy , the generated JAR file name is db-hbase-coprocessorDeploy.jar . Ensure that you use the same identifier that you used in the CoprocessorPath parameter of the configuration file.
--rule	matching_rules_file_name	Optional. Absolute path and file name of the matching rules file that you create.
--coprocessor		Indicates that the script generates the coprocessor JAR file.

Deploy the generated JAR file to the directory that you configured for the

CoprocessorPath

parameter in the configuration file.

For example, the following command deploys a JAR file to an HDFS directory:

hadoop fs -put -f db-hbase-coprocessorDeploy.jar /user/cloudera/
