Hi,
In Reduce phase when i write to Hbase Table "PFTableNa"
context.write(null , put);
Eclipse say me:
*"The method write(ImmutableBytesWritable, Writable) in the type
TaskInputOutputContext<Text,BytesWritable,ImmutableBytesWritable,Writable>
is not applicable for the arguments (null, Put)"*
*put *is org
<eclipse-javadoc:%E2%98%82=LoadUnico/C:%5C/Users%5C/sdigregorio%5C/workspace-luna%5C/hbase-client-0.96.0-hadoop1.jar%3Corg>

row)
byte[] rowkey = key.getBytes();
Put put = new Put(rowkey);
the signature of the reduce method:
reduce( Text key,Iterable<BytesWritable> values, Context context)
and
public static class Reduce extends TableReducer<Text, BytesWritable,
ImmutableBytesWritable>{
in the main method:
Configuration conf = HBaseConfiguration.create();
Job job = new Job(conf, "LetturaFileHDFS2HBase");
...
TableMapReduceUtil.initTableReducerJob("PFTableNa", Reduce.class, job);
Thanks a lot
Silvio
