Description: 
When doing a full rebuild (or initial async build) of a local or global index 
using IndexTool and PhoenixIndexImportDirectMapper, or doing a synchronous 
initial build of a global index using the index create DDL, we generate the 
index mutations by using an UPSERT SELECT query from the base table to the 
index.

The timestamps of the mutations use the default HBase behavior, which is to 
take the current wall clock. However, the timestamp of an index KeyValue should 
use the timestamp of the initial KeyValue in the base table.

Having base table and index timestamps out of sync can cause all sorts of weird 
side effects, such as if the base table has data with an expired TTL that isn't 
expired in the index yet. Also inserting old mutations with new timestamps may 
overwrite the data that has been newly overwritten by the regular data path 
during index build, which would lead to data loss and inconsistency issues.

  was:
When doing a full rebuild (or initial async build) on an index using the 
IndexTool and PhoenixIndexImportDirectMapper, we generate the index mutations 
by creating an UPSERT SELECT query from the base table to the index, then 
taking the Mutations from it and inserting it directly into the index via an 
HBase HTable. 

The timestamps of the Mutations use the default HBase behavior, which is to 
take the current wall clock. However, the timestamp of an index KeyValue should 
use the timestamp of the initial KeyValue in the base table.

Having base table and index timestamps out of sync can cause all sorts of weird 
side effects, such as if the base table has data with an expired TTL that isn't 
expired in the index yet.

> When doing a full rebuild (or initial async build) on an index using the 
> IndexTool and PhoenixIndexImportDirectMapper, we generate the index mutations 
> by creating an UPSERT SELECT query from the base table to the index, then 
> taking the Mutations from it and inserting it directly into the index via an 
> HBase HTable. 
> The timestamps of the Mutations use the default HBase behavior, which is to 
> take the current wall clock. However, the timestamp of an index KeyValue 
> should use the timestamp of the initial KeyValue in the base table.
> Having base table and index timestamps out of sync can cause all sorts of 
> weird side effects, such as if the base table has data with an expired TTL 
> that isn't expired in the index yet.
