Zoltan Haindrich commented on HIVE-18448:
-----------------------------------------

I always wanted to file a ticket for this...its sometimes problematic to keep the index related things around; since 3.0 will be a major release currently we might have a chance to drop support for it.

> 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.
