[jira] [Commented] (CURATOR-34)
CuratorFramework.create().creatingParentsIfNeeded().forPath() throws
NodeExistsException if node exists
[ https://issues.apache.org/jira/browse/CURATOR-34?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=13769609#comment-13769609 ]
John Vines commented on CURATOR-34:
-----------------------------------
Perhaps there should be ignoreIfExists() and/or setDataIfExists flag(s) that can be used? I can understand where Nandor is coming from, as this request and createParentsIfNeeded are in the same family of "I just want this node to exist (optionally with this data) now".

> I think that NodeExistsException should be ignored in CreateBuilderImpl. In the try and in the NoNodeException catch block as well.
