hive> set hive.llap.execution.mode=none;
to change into llap mode use the following command
hive> set hive.llap.execution.mode=all;
LLAP is an optional daemon process running on multiple nodes, that provides the following
- Caching and data reuse across queries with compressed columnar data in-memory
- Multi threaded execution including reads with predicate pushdown and hash join
- High throughput IO using Asynch IO Elevator with dedicated thread and core per disk
- Granular column level security across applications
