Enrico Olivelli updated ZOOKEEPER-933: -------------------------------------- Fix Version/s: (was: 3.5.6) > Remove wildcard QuorumPeer.OBSERVER_ID > --------------------------------------- > > Key: ZOOKEEPER-933 > URL: https://issues.apache.org/jira/browse/ZOOKEEPER-933 > Project: ZooKeeper > Issue Type: Sub-task > Reporter: Vishal Kher > Priority: Major > Fix For: 3.6.0, 3.5.7 > > > 1. I have a question about the following piece of code in QCM: > if (remoteSid == QuorumPeer.OBSERVER_ID) { > /* * Choose identifier at random. We need a value to identify * the > connection. */ > remoteSid = observerCounter--; > LOG.info("Setting arbitrary identifier to observer: " + remoteSid); > } > Should we allow this? The problem with this code is that if a peer > connects twice with QuorumPeer.OBSERVER_ID, we will end up creating > threads for this peer twice. This could result in redundant > SendWorker/RecvWorker threads. > I haven't used observers yet. The documentation > http://hadoop.apache.org/zookeeper/docs/r3.3.0/zookeeperObservers.html > says that just like followers, observers should have server IDs. In > which case, why do we want to provide a wild-card? -- This message was sent by Atlassian Jira (v8.3.2#803003)
