------------------------------------
Summary: Compactions may leak memory when unauthorized
Key: HIVE-22700
URL: https://issues.apache.org/jira/browse/HIVE-22700
Project: Hive
Issue Type: Bug
Components: Hive
Reporter: Laszlo Pinter
Assignee: Laszlo Pinter
Initiator class determines compaction type periodically. Initiator either runs
as hive user or impersonates the owner of the table. When impersonation is
used, Initiator#checkForCompaction may leak memory. If impersonation
(ugi.doAs()) call fails, FileSystem.closeAllForUGI does not run, therefore does
not clean the file system cache.
