The warning are generated by [TabletServerLogger.java line
341|https://github.com/apache/accumulo/blob/4e91215f101362ef206e9f213b4d8d12b3f6e0e2/server/tserver/src/main/java/org/apache/accumulo/tserver/log/TabletServerLogger.java#L341]
when a write ahead log is closed. Write ahead logs are closed as part of
normal operations as seen on [TabletServerLogger.java line
386|https://github.com/apache/accumulo/blob/4e91215f101362ef206e9f213b4d8d12b3f6e0e2/server/tserver/src/main/java/org/apache/accumulo/tserver/log/TabletServerLogger.java#L386].
There should not be a warning when this happens. This is caused by changes
made for ACCUMULO-4777. Before these changes this event was logged at debug.
At this time, these changes have not been released. It would be nice to fix
this before releasing 1.7.4
