=46or Curator, I suggest you use this form:

client.create().creatingParentsIfNeeded().forPath(path).=C2=A0

You shouldn=E2=80=99t ever need to catch the node exists exception in thi=
s case. But, of course, it depends on your use case. Also, have a look at=
 how Curator implements various recipes for examples.

The trouble is that it is never caught and zookeeper pollutes my producti=

I have tried in the past to fix my code so these exceptions are never =20
