Divya Bhargov created HAWQ-1621: ----------------------------------- Summary: Call FileSystem.closeAllForUGI at the end of request when PXF impersonation is on Key: HAWQ-1621 URL: https://issues.apache.org/jira/browse/HAWQ-1621 Project: Apache HAWQ Issue Type: Improvement Components: PXF Reporter: Divya Bhargov Assignee: Ed Espino
Due to open Hadoop JIRA: https://issues.apache.org/jira/browse/HDFS-3545 , when PXF impersonation is on, proxy UGIs created for each request produce FileSystem cache entries that are not removed when the request is over. This causes OutOfMemory errors since the entries are never removed. To remove the entries and clean the cache, we should call FileSystem.closeAllForUGI at the end of request when PXF impersonation is on. -- This message was sent by Atlassian JIRA (v7.6.3#76005)
