[jira] [Comment Edited] (CASSANDRA-8743) NFS doesn't behave on
Windows
[ https://issues.apache.org/jira/browse/CASSANDRA-8743?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=16453978#comment-16453978 ]

------------------------------------------------------------------------
As we are facing the same issue with Cassandra 2.1.18 and NFS (although on Linux and not Windows) I wonder if there was any movement in the last years/months which has not been commented on this ticket? Thanks.
What might happen is (although no evidence, due to lack of test environment):
* Cassandra deletes the snapshotted SSTable (symlink) without closing the file handle
* NFS created a hidden file ".nfsSOMETHING" for a deleted file where a process still have a file handle open
* Cassandra then will fail upon deleting the snapshot directory
Just a very wild, speculative guess.
