Specified config does not exist in ZooKeeper (Log Search is broken)

jpetro416 — Wed, 16 May 2018 00:46:28 GMT

Fresh cluster (2.6.4) was working, restarted zookeeper and now seeing multiple errors. How can I fix this and why doesn't Solr just send new data to zookeeper?

For those facing this issue with hadoop_logs (Log Search)

Delete the Log Search service from Ambari UI
Go into the zookeeper shell /usr/hdp/current/zookeeper-client/bin/zkCli.sh
rmr /infra-solr/configs/hadoop_logs
Open up solr and delete the shards/collection for hadoop_logs
SSH into your SOLR servers as root/sudo
Delete /opt/ambari_infra_solr/data/hadoop_logs*
Make sure you have at least 2 instances of SOLR installed
Install Log Search on a new node (a SOLR instance should be installed on this node as well)
Log search should be running now
