@anoopsjohn The patch you have send cannot apply. Can you make patch once again after rebase and send me please?
Thanks.

A basic impl is done and pushed to hbase-98 branch.
A single arbitrary index can be created on a table. User can pass all the cfs of this table which need to be indexed. During writes we will index each and every arbitrary Q in that cfs. Each of the cf:q will be indexed with one entry to index table.
During Scan based on the condition, the arbitrary index also will get used.
There are still some more TODOs
During puts only we will add index entries. Deletion of index data on table data delete (for arbitrary index) is not done in this version. (Well this wont create any incorrect results on Scan)
Only SCVF condition with equals condition is supported on arbitrary index now. Range condition support is yet to add
Some more clear validations required on table create/modify
Also one more limitation is when a table is having arbitrary index added on it, we don't allow creating any other index on this same table. It can be supported in later versions. The use case might not be really there I believe. Because the Q names on the table are arbitrary any way.
