> Attachments: 0001-Added-MultithreadedTableMapper-HBASE-5166.patch,

> Remaining Estimate: 0.5h
>
> There is no MultiThreadedTableMapper in hbase currently just like we have a
> MultiThreadedMapper in Hadoop for IO Bound Jobs.
> UseCase, webcrawler: take input (urls) from a hbase table and put the content
> (urls, content) back into hbase.
> Running these kind of hbase mapreduce job with normal table mapper is quite
> slow as we are not utilizing CPU fully (N/W IO Bound).
> Moreover, I want to know whether It would be a good/bad idea to use HBase for
> these kind of usecases ?.
