Edward Yoon commented on HADOOP-2339:
-------------------------------------
'columnfamily', 'columnfamily:specified_qualifer' delete function is important
thing.
I'm not bothering to make a example.
Also, I thought it should be work as inter-row wise partitioned sub structre
parallelism.
But, now shell is 0.0.1 version.
Imagine the processing-speed:increment by row-count:increment 2d plots of
scanner and mapreduce,
start points of processing-speed dimension and slopes will be different.
So, I thought the cross point find algorithm for the most faster automatical
processing.
'Slow Performance' can't touch the grammar rules.
