Ádám Szita commented on HIVE-23258:
-----------------------------------
[~belugabehr] , by looking at this patch - I think users setting BoneCP in
their confs will see failure starting up Hive right?
If so and their not being automatically moved to Hikari I think we should set
the backward incompatible label on this one.

> BoneCP is a Java JDBC connection pool implementation that is tuned for high
> performance by minimizing lock contention to give greater throughput for your
> application ... but SHOULD NOW BE CONSIDERED DEPRECATED in favour of HikariCP.

> The default in Hive 3.x is already HikariCP, so just remove BoneCP in 4.x
