> Project: Apache Curator

> Affects Versions: 2.7.0
> Environment: operating system:ubuntu

> Priority: Blocker
> Fix For: 3.0.0, 2.7.2

> Original Estimate: 168h

> We use LeaderLatch for leader election within our several zookeeper
> clients,but sometimes our leaderLatch stopped to work due to a error
> "Background exception was not retry-able or retry gave up
> java.lang.IllegalArgumentException: Path must start with / characte".
> To found the reason we tracked the execution of program in class LeaderLatch
> with debug mode,we found the code "setNode(event.getName());" in line 487 of
> LeaderLatch.class in which "event.getName()" code sometimes didn't return the
> full path of the znode but only return the last part of the full path,like
> "_c_b1097329-4a77-493b-806c-5c888067eeab-latch-0000004068", but the full path
> should be
> "/api1/leaders/_c_b1097329-4a77-493b-806c-5c888067eeab-latch-0000004068".
> So the when
> event.getName()=="_c_b1097329-4a77-493b-806c-5c888067eeab-latch-0000004068",
> the program will fail to go through the codes below:
> 1.LeaderLatch.checkLeadership() line 526
> 2.ZKPaths.getNodeFromPath() line 61
> 3.PathUtils.validatePath(path) line 46
> And then the LeaderLatch stopped to work.
