Enis Soztutar commented on HBASE-10688:
---------------------------------------
Thanks Lars for looking.
bq. Since the purpose of this is to set/remove znodes it might be better to
fail with an exception if that fails rather then failing silently.
We are using ZkUtil.createAndFailSilent() and deleteAndfailSilent() because it
might happen that the node got added or removed by someone else. They will only
swallow node exists / node does not exists exceptions, not generic zookeeper
exceptions.
