> {{--use_krpc}} was introduced in 2.9.0 during development of adopting KRPC 
> for DataStream services (IMPALA-2567). It was initially hidden and set to 
> false as it wasn't fully implemented yet. Since 2.12.0 and 3.0, this flag is 
> set to true by default. Going forward, we will port more services to KRPC and 
> it's become very burdensome to keep both Thrift RPC and KRPC implementation 
> for converted RPCs. The best route forward is to drop this flag for 3.0+ 
> releases.
