Don't think so, the default behaviour at 4), to my knowledge,is to wait 3 minutes (leaderVoteWait) for all replicas to come up to avoid electing a leader with stale data. So the observed behaviour is unexpected to me
I created a cluster of 2 nodes copying the server dir to node1 and node2 and using those as solrhome for the nodes created the collection with bin/solr create -c test so it's using the builtin schemaless configuration there's nothing custom, should be all pretty standard 2015-10-15 17:42 GMT+02:00 Alessandro Benedetti <benedetti.ale...@gmail.com> : > Hi Matteo, > > On 15 October 2015 at 16:16, Matteo Grolla <matteo.gro...@gmail.com> > wrote: > > > Hi, > > I'm doing this test > > collection test is replicated on two solr nodes running on 8983, 8984 > > using external zk > > > > 1)turn OFF solr 8984 > > 2)add,commit a doc x con solr 8983 > > 3)turn OFF solr 8983 > > 4)turn ON solr 8984 > > > At this point 8984 will be elected leader, because only element in the > cluster, it can not do anything to recover, so it will not replicate Doc x > > > 5)shortly after (leader still not elected) turn ON solr 8983 > > > I assume that even if you are not able to see it, actually the leader > election was already starting, not taking in consideration 8983 > > > 6)8984 is elected as leader > > > As expected > > > 7)doc x is present on 8983 but not on 8984 (check issuing a query) > > > This is expected as well. > > It is a very edge case, but i expect at the current status, the behaviour > you are obtaining is the expected one. > Probably the leader election should become smarter, for example, any time a > node came back to the cluster it should be checked, and in the case it > should be the leader a new election triggered. > Just thinking loud :) > > > > > > > attached are the logs of both solr > > > > BTW I'm using java 1.8.045 on osx yosemite and solr 5.2.1 seems much > > slower to startup than solr 4.10.3. it seems waiting on something > > > > I can not see any attached file, do you have any suggester in place ? > Anyway is weird as I assume you kept the solrconfig.xml the same. > Can you list the components you are currently using ? > > Cheers > > > > -- > -------------------------- > > Benedetti Alessandro > Visiting card - http://about.me/alessandro_benedetti > Blog - http://alexbenedetti.blogspot.co.uk > > "Tyger, tyger burning bright > In the forests of the night, > What immortal hand or eye > Could frame thy fearful symmetry?" > > William Blake - Songs of Experience -1794 England >
