Enclosing class:

CorpusTableMR

public abstract static class CorpusTableMR.CorpusTableMapper<K,V>
extends org.apache.hadoop.hbase.mapreduce.TableMapper<K,V>

A simple base class for any CorpusTableMR job. Most implementations need only implement #map(ImmutableBytesWritable, Result, Context). Those that need more than just a CorpusTable should override #setup(Context, Configuration) to create any additional data structures or data sources.

Method Detail

setup

public void setup(org.apache.hadoop.mapreduce.Mapper.Context context)
           throws IOException,
                  InterruptedException

Initializes the CorpusTable for this CorpusTableMR.CorpusTableMapper and calls #setup(Context, Configuration).

Overrides:

setup in class org.apache.hadoop.mapreduce.Mapper<org.apache.hadoop.hbase.io.ImmutableBytesWritable,org.apache.hadoop.hbase.client.Result,K,V>

Throws:

IOException

InterruptedException

setup

protected void setup(org.apache.hadoop.mapreduce.Mapper.Context context,

              throws IOException,
                     InterruptedException

Sets up any addition data classes or information needed by the CorpusTableMR.CorpusTableMapper. By default, this does nothing.

Throws:

IOException
