James Taylor commented on PHOENIX-1609:
---------------------------------------
Good call, [~sergey.b]. Conceptually it's the same idea. We can have
{code}
CREATE INDEX idx ON tbl(v1,v2) ASYNC
DROP TABLE tbl ASYNC
{code}
> MR job to populate index tables

> Often, we need to create new indexes on master tables way after the data
> exists on the master tables. It would be good to have a simple MR job given
> by the phoenix code that users can call to have indexes in sync with the
> master table.
> Users can invoke the MR job using the following command
> hadoop jar org.apache.phoenix.mapreduce.Index -st MASTER_TABLE -tt
> INDEX_TABLE -columns a,b,c
> Is this ideal?
