Hi,=A0

=A0 I am new to hbase and am trying to achieve = the following.

I am reading data from hdfs in mapp= er and parsing it..

So, in reducer I want my outpu= t to write to hbase instead of hdfs

But here is the thing.

public static cla= ss MyTableReducer extends TableReducer<Text, Text, ImmutableBytesWritabl= e> =A0{

public voi= d reduce(Text key, Iterable<Text> values, Context context) throws IOE= xception, InterruptedException {

= int type =3D getType(values.toString());

if (type =3D=3D 1) /= / put data to table 1

= if (type=3D=3D2) // put data to table 2 =A0 =A0=

=A0 }

}

How do I do this?

Thanks
