How to set number of mappers when using HBaseStorage

[leiwang...@gmail.com]

When using HBaseStorage to read data from hbase table, there will be one mapper 
for one region.
Howerver, my hbase table has more than 1000 regions and only 80 mappers 
capacity.
Is there a way to set the number of mappers when using HBaseStorage?

Thanks,
Lei
