Description

We have been working on implementing secondary index in HBase and open sourced on hbase 0.94.8 version.
The project is available on github.
https://github.com/Huawei-Hadoop/hindex

This Jira is to support secondary index on trunk(0.98).

Following features will be supported.

• multiple indexes on table,
• multi column index,
• index based on part of a column value,
• equals and range condition scans using index, and
• bulk loading data to indexed table (Indexing done with bulk load)

Most of the kernel changes needed for secondary index is available in trunk. Very minimal changes needed for it.
