Joe McDonnell updated IMPALA-6876: ---------------------------------- Target Version: Impala 4.0 (was: Impala 2.13.0, Impala 3.4.0) > Entries in CatalogUsageMonitor are not cleared after invalidation > ----------------------------------------------------------------- > > Key: IMPALA-6876 > URL: https://issues.apache.org/jira/browse/IMPALA-6876 > Project: IMPALA > Issue Type: Bug > Components: Catalog > Affects Versions: Impala 3.0, Impala 2.12.0 > Reporter: Dimitris Tsirogiannis > Priority: Major > Labels: memory-leak, ramp-up > > The CatalogUsageMonitor in the catalog maintains a small cache of references > to tables that: a) are accessed frequently in the catalog and b) have the > highest memory requirements. These entries are not cleared upon server or > table invalidation, thus preventing the GC from collecting the memory of > these tables. We should make sure that the CatalogUsageMonitor does not > maintain entries of tables that have been invalidated or deleted. -- This message was sent by Atlassian Jira (v8.3.4#803005) --------------------------------------------------------------------- To unsubscribe, e-mail: issues-all-unsubscr...@impala.apache.org For additional commands, e-mail: issues-all-h...@impala.apache.org
