--------------------------------------
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.
