------------------------------------------

[~jamestaylor]
   Based on the comments received above, I am attaching a patch  .  Users can 
create an index in async mode and manually trigger the MR job.
{code}
a) Create an index in async mode.
      CREATE INDEX idx ON tbl (v1,v2) ASYNC
b) Trigger the job
      hadoop jar phoenix-4.3.0-client.jar  
org.apache.phoenix.mapreduce.index.IndexTool  -dt TBL -it IDX -op /tmp/pindx

{code}

I will attach a patch for various test cases after your review.

> 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?
