org.apache.hadoop.conf.Configured

com.mapr.db.mapreduce.tools.ImportJSON

All Implemented Interfaces:

org.apache.hadoop.conf.Configurable, org.apache.hadoop.util.Tool

public class ImportJSON
extends org.apache.hadoop.conf.Configured
implements org.apache.hadoop.util.Tool

This utility is used when importing JSON text files into a MapR Document-DB Table. If the utility is used with the '-bulkload' option set to 'true', the admin must clear the bulkload flag on the MapR-DB table after the import is complete, before the table can begin serving data, using the command 'maprcli table edit -path -bulkload false' on the server.
