public static void configureCfRenaming(org.apache.hadoop.conf.Configuration conf,
Map<String,String> renameMap)
Sets a configuration property with key CF_RENAME_PROP in conf that tells
the mapper how to rename column families.
Alternately, instead of calling this function, you could set the configuration key
CF_RENAME_PROP yourself. The value should look like
srcCf1:destCf1,srcCf2:destCf2,..... This would have the same effect on the mapper behavior.
conf - the Configuration in which the CF_RENAME_PROP key will be
setrenameMap - a mapping from source CF names to destination CF names
public static void addFilterAndArguments(org.apache.hadoop.conf.Configuration conf,
Class<? extends Filter> clazz,
List<String> args)
conf - Configuration to update (will be passed to the job)clazz - Filter subclass to instantiate on the server.args - List of arguments to pass to the filter on instantiation
public static org.apache.hadoop.mapreduce.Job createSubmittableJob(org.apache.hadoop.conf.Configuration conf,
String[] args)
throws IOException
conf - The current configuration.args - The command line parameters.
IOException - When setting up the job fails.
public static void main(String[] args)
throws Exception
args - The command line parameters.
Exception - When running the job fails.
