             Summary: Include the size of tableLoadingBarrier_ in TableLoadingMgr logging
                 Key: IMPALA-11866
                 URL: https://issues.apache.org/jira/browse/IMPALA-11866
             Project: IMPALA
          Issue Type: Improvement
          Components: Frontend
    Affects Versions: Impala 4.3.0
            Reporter: Joe McDonnell


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

 
{noformat}
      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) {{noformat}
[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.
