mapreduce, hbase and scan

I have a MapReduce job that extends the TableMapper class. I use the TableMapperReduceUtil initTableMapperJob to setup the initial scan which works fine. Based on the rowkey retrieved from the Scan I want to run a Get (using a rowkey which is a value in the initial Scan row) on the same table within my MapReduce Map method. How do I access the Hbase connection to the same table from within the Map method?

Probably you can create a new connection in this manner:

Configuration config = context.getConfiguration();
Connection conn = ConnectionFactory.createConnection(config);

But I think in your case it will be easier to use Spark on HBase
