MultiThreaded Table Mapper analogous to MultiThreaded Mapper in hadoop
----------------------------------------------------------------------
Key: HBASE-5166
URL: https://issues.apache.org/jira/browse/HBASE-5166
Project: HBase
Issue Type: Improvement
Reporter: Jai Kumar Singh
Priority: Minor
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 ?.
