Hi All, I try to divide some data into partitions explicitly (like regions of Hbase). I wonder the following way to do is the best method.
For example, when we assume a block size 64MB, a file potion corresponding to 0~63MB is allocated to first block? I have three questions as follows: Is the above method valid? Is it the best method? Is there alternative method? Thank in advance. -- Hyunsik Choi Database & Information Systems Group Dept. of Computer Science & Engineering, Korea University On Mon, 2008-11-24 at 20:44 -0800, Mahadev Konar wrote: > Hi Dennis, > I don't think that is possible to do.
