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
