Summary: 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 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)
