Hi all,
maybe somebody could give me advice in the following
situation:
Currently HBase Scan interface provides ability to set up
only first and last rows for MR scanning. Is it any way to
get multiple ranges into the map input?
For example let's assume I have following table:
key value
1 v1
2 v2
3 v3
4 v4
5 v5
What I need is to get for example [1,2) and [4,5) ranges
as input for my Map task. Actually I need this for the
performance optimization.
Any advice?
Thanks.
