方法详细资料

map

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

覆盖:

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

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.

processKV

protected void processKV(ImmutableBytesWritable key,
             Result result,
             org.apache.hadoop.mapreduce.Mapper.Context context,
             Put put,
             Delete delete)
                  throws IOException,
                         InterruptedException

抛出:

IOException

InterruptedException

addPutToKv

protected void addPutToKv(Put put,
              Cell kv)
                   throws IOException

抛出:

IOException

setup

public void setup(org.apache.hadoop.mapreduce.Mapper.Context context)

覆盖:

setup 在类中 org.apache.hadoop.mapreduce.Mapper<ImmutableBytesWritable,Result,ImmutableBytesWritable,Mutation>
