    Description

      The logging in TableLoadingMgr.java already logs the size of tableLoadingDeque_ and loadingTables_ here:

       

            try {
        LOG.info("Loading metadata for table: " +
            tblName_.db_name + "." + tblName_.table_name);
        LOG.info(String.format("Remaining items in queue: %s. Loads in progress: %s",
            tableLoadingDeque_.size(), loadingTables_.size()));
        tbl = tblTask_.get();
      } catch (Exception e) {

      https://github.com/apache/impala/blob/master/fe/src/main/java/org/apache/impala/catalog/TableLoadingMgr.java#L71

      It would be useful to also log the size of tableLoadingBarrier_ as well, because that structure is crucial to correctness and it is otherwise difficult to observe.
