map

public void map(ImmutableBytesWritable row,
       Result value,
       org.apache.hadoop.mapreduce.Mapper.Context context)
         throws IOException

Map method that compares every scanned row with the equivalent from a distant cluster.

覆盖:

map 在类中 org.apache.hadoop.mapreduce.Mapper<ImmutableBytesWritable,Result,ImmutableBytesWritable,Put>

参数:

row - The current table row key.

value - The columns.

context - The current context.

抛出:

IOException - When something is broken with the data.

cleanup

protected void cleanup(org.apache.hadoop.mapreduce.Mapper.Context context)

覆盖:

cleanup 在类中 org.apache.hadoop.mapreduce.Mapper<ImmutableBytesWritable,Result,ImmutableBytesWritable,Put>
