A replica of that type (TLOG) should be capable of becoming leader. The PULL replica type is the one that cannot become leader. > On 7/2/2018 7:54 PM, Joe Obernberger wrote: >> Hi - On startup, I'm getting the following error.

Any ideas? <snip> >> Caused by: org.apache.zookeeper.KeeperException$NoNodeException: >> KeeperErrorCode = NoNode for >> /collections/UNCLASS_30DAYS/leaders/shard6/leader This is saying that a specific path (/collections/UNCLASS_30DAYS/leaders/shard6/leader) does not exist in the ZooKeeper database. I do not know why it doesn't exist. You may need to create the znode represented by that path. If you use the same zkHost option for the command as you have for Solr itself, you can create the path with the "zk mkroot" command on the control script: https://lucene.apache.org/solr/guide/6_6/solr-control-script-reference.html#solr-control-script-reference After creating that znode, it is probably a good idea to restart one of the Solr nodes with a shard for that collection. It is possible that it still might not work, but it should change the error message even if it doesn't work, and we can go from there to come up with additional ideas. Thanks, Shawn
