ASF GitHub Bot commented on FLINK-5659: --------------------------------------- Github user zentol commented on the issue: https://github.com/apache/flink/pull/3219 That could work. Are you worried about the added sleep in case of an `DirectoryNotEmptyException`? > FileBaseUtils#deleteFileOrDirectory not thread-safe on Windows > -------------------------------------------------------------- > > Key: FLINK-5659 > URL: https://issues.apache.org/jira/browse/FLINK-5659 > Project: Flink > Issue Type: Bug > Affects Versions: 1.2.0, 1.3.0 > Reporter: Chesnay Schepler > Assignee: Chesnay Schepler > Priority: Trivial > > The {code}FileBaseUtils#deleteFileOrDirectory{code} is not thread-safe on > Windows. > First you will run into AccessDeniedExceptions since one thread tried to > delete a file while another thread was already doing that, for which the file > has to be opened. > Once you resolve those exceptions (by catching them double checking whether > the file still exists), you run into DirectoryNotEmptyExceptions since there > is some wacky timing/visibility issue when deleting files concurrently. -- This message was sent by Atlassian JIRA (v6.3.4#6332)
