Zoltan Haindrich commented on HIVE-18448:
-----------------------------------------
patch#1: is bulk removal only; I plan to do the following in separate changes:
* remove support from metastore as well
* some parts of the index classes were used from StorageHandlers
(hbase/accumulo) - I think that should be investigated separately - this patch
may just hide those changes so I've not touched it
> Drop Support For Indexes From Apache Hive

> If a user needs to look up a small subset of records quickly, they can use
> Apache HBase, if they need fast retrieval of larger sets of data, or fast
> joins, aggregations, they can use Apache Impala. It seems to me that Hive
> indexes do not serve much of a role in the future of Hive.
> Even without moving workloads to other products, columnar file formats with
> their statistics achieve similar goals as Hive indexes.
> Please consider dropping Indexes from the Apache Hive project.
