I have found the problem: the skip-scan-join did not call ResultIterator.close() for sub-plan iterators. A skip-scan-join does not create a hash cache itself, but may contain sub-plans that do (in which case they are a normal join). ResultIterator.close() is called within HashCacheClient.addHashCache(), so a normal join does not have this problem. > Subqueries are not freeing hash cache > ------------------------------------- > > Key: PHOENIX-2556 > URL: https://issues.apache.org/jira/browse/PHOENIX-2556 > Project: Phoenix > Issue Type: Bug > Reporter: James Taylor > Assignee: Maryann Xue > Fix For: 4.7.0 > > Attachments: PHOENIX-2556.patch, PHOENIX-2556_wip.patch > > > Subqueries are only freeing some of the server-side hash cache memory, leading to essentially a kind of memory leak. -- This message was sent by Atlassian JIRA (v6.3.4#6332)
