-----------------------------------
Summary: Don't attempt to delete parent directory on S3
Key: FLINK-7266
URL: https://issues.apache.org/jira/browse/FLINK-7266
Project: Flink
Issue Type: Bug
Components: Core
Affects Versions: 1.3.1
Reporter: Stephan Ewen
Assignee: Stephan Ewen
Fix For: 1.4.0, 1.3.2
Currently, every attempted release of an S3 state object also checks if the
"parent directory" is empty and then tries to delete it.
Not only is that unnecessary on S3, but it is prohibitively expensive and for
example causes S3 to throttle calls by the JobManager on checkpoint cleanup.
The {{FileState}} must only attempt parent directory cleanup when operating
against real file systems, not when operating against object stores.
