Description

Recent changes like 694d72ea9bd1543e2bf1b0a2edf2af213f89a35b and IMPALA-4172 changed the behavior of logging, in particular, during table loading. The new logging is drastically reduced, but unfortunately, insufficient for any meaningful debugging of issues with table loading. We should restore/improve important log messages without increasing the default log volume too much.
