Prasanth Jayachandran commented on HIVE-12237:
----------------------------------------------
The strings will be concatenated during compile time and put into constant
pool. There is no runtime penalty for concatenation. Also isDebug/isInfo is
done internally and will be inlined in most cases. Theoretically it should give
better performance.
> Use slf4j as logging facade
