Quanlong Huang updated IMPALA-11866:
------------------------------------
Labels: observability (was: )
> 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
> Priority: Minor
> Labels: observability
>
> 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.
