[jira] [Comment Edited] (NIFI-2128) NiFi service fails to start
with FileAlreadyExistsException when configured to use a directory that is
symlink
[ https://issues.apache.org/jira/browse/NIFI-2128?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=17290192#comment-17290192 ]

---------------------------------------------------------------
I have the same issue, I think it was seen previously with "conf" directory here:
https://issues.apache.org/jira/browse/NIFI-1746
The patch that fixes it last time is:
[https://github.com/apache/nifi/commit/5625686/]
I'm not sure where to apply it in this case though, but it looks like this bug will happen at every place where:
{code:java}
Files.createDirectories(flowXml.getParent());
{code}
exists and needs to be replaced with:
{code:java}
// createDirectories would throw an exception if the directory exists but is a symbolic link
if (Files.notExists(flowXml.getParent())) {
Files.createDirectories(flowXml.getParent());
}
{code}
