Subject [jira] Commented: (HADOOP-2339) [Hbase Shell] Delete command with no WHERE clause
Date Tue, 11 Dec 2007 23:04:44 GMT

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.
