tera vs hbase

roadmap:

- [x] setup hbase 1.2.3 on hadoop 2.6
- [ ] hbase performance test on ycsb (headline 11.14)
- [ ] tera performance test on ycsb (headline 11.20)

计划：
- [x] 在hadoop 2.6上搭建hbase 1.2.3；
- [ ] 使用ycsb测试hbase性能；（dead line：11.14）
- [ ] 开发ycsb上对接tera的接口层；（dead line：11.20），并提pr到ycsb；

The issue is an old roadmap for comparing HBase and Tera with YCSB. Start by reviewing the listed HBase setup and the YCSB performance-test goals; the work is done when both benchmarks run and the Tera YCSB interface is developed and proposed upstream.
