Summary: Clear Context Map of Paths to ContentSummary
Key: HIVE-19834
URL: https://issues.apache.org/jira/browse/HIVE-19834
Project: Hive
Issue Type: Improvement
Components: HiveServer2
Affects Versions: 2.3.2, 3.0.0, 4.0.0
Reporter: BELUGA BEHR
Attachments: HIVE-19834.1.patch
The {{Context}} class has a {{clear}} method which is called. During the
method, various files are deleted and in-memory maps are cleared. I would like
to propose that we clear out an additional in-memory map structure that may
contain a lot of data so that it can be GC'ed asap. This map contains mapping
of "File Path"->"Content Summary". For a query with a large file set, this can
be quite large.
