Key: HBASE-1183
URL: https://issues.apache.org/jira/browse/HBASE-1183
Project: Hadoop HBase
Issue Type: Improvement
Components: util
Reporter: Jonathan Gray
Assignee: Jonathan Gray
Priority: Minor
Fix For: 0.19.1, 0.20.0
For HBASE-1172 and other functionality coming soon, we need to be able to take
a [start,stop) range and divide it into chunks.
For example, we have 10 regions but want to run 30 maps. We need to divide
each region into three key ranges for the start/stop of each scanner.
Implementing using java.math.BigInteger
Will also include a couple additional helpers in Bytes to make life easy.
