Subject [jira] [Commented] (FLINK-2945) Shutting down a local Flink instance on Windows doesn't clean up blob cache
Date Tue, 03 Nov 2015 07:20:27 GMT

    [ https://issues.apache.org/jira/browse/FLINK-2945?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=14986830#comment-14986830
] 

Stephan Ewen commented on FLINK-2945:
-------------------------------------

This means probably that there are still open file streams when we aim to delete the directory.
Since windows blocks the files from removal from the directory, the shutdown fails. We would
need to make sure all streams are closed before the directory is removed.
