I am trying to implement solrcloud.I foollowed doc from official resource https://cwiki.apache.org/confluence/display/solr/Getting+Started+with+SolrCloud .It works fine with embeded zookeper but it is recomended to use external zookeper. I insalled zookeper on my system created data dictionary zookeper on my home folder.I created sub folders named 1 and 2 and created myid file with text 1 and two respectively i each folder as mentioned in doc.I created config files for zookeper zoo.cnfg
clientPort=2181
initLimit=5
syncLimit=2
server.1=localhost:2879:3879
server.2=localhost:2888:3888
and zoo2.cnfg
initLimit=5
syncLimit=2
clientPort=2182
server.1=localhost:2878:3878
server.2=localhost:2888:3888
Next I run cd
bin/zkServer.sh start zoo.cfg
bin/zkServer.sh start zoo2.cfg
And its started sucessfully. next I run
bin/solr start -e cloud -z localhost:2181,localhost:2182
system ask me no of shards etc like in getting started i select port for node1 8990 and for node 2 8991. It gives error
Waiting to see Solr listening on port 8991 [/] Still not seeing Solr listening on 8991 after 30 seconds!
