Subject [jira] [Commented] (CURATOR-319) NodeCache recreates deleted parents of the node being cached
Date Mon, 02 May 2016 18:05:13 GMT


Tommy Becker commented on CURATOR-319:

Yeah, I guess it's not entirely straightforward. I guess in my mind, something labeled a cache
should not modify ZK at all. Maybe there could be a mode where an exception is thrown when
the cache is started if the node that it's caching isn't there. And then if it subsequently
goes away, just returning null for the contents.

> Starting with Curator 2.10.0, the NodeCache will spontaneously re-create parents of the
node being cached if one of them is deleted.  As an example, if there is a NodeCache watching
node /a/b/c and node b is deleted, the cache will immediately recreate node b (but not c)
when the change is processed. This seems to stem from this commit:
> This was not the behavior prior to 2.10.0, and seems pretty unexpected.
