We have a working standalone Cloudera solution with Zookeeper, HDFS, Solr, Accumulo and Kafka. When trying to clone this to another VM, we can get everything to work with the new IP, but accumulo tablets are erroring with trying to reach the original hostname. Does anyone know whether this is embedded in the HDFS, or is there a config entry we are missing. The error is below: The original host was cafe-144, the clone was cafe-191, I edited the names, so may be missing, but both hostnames on the servers are configured as well as FQDN.
exception trying to assign tablet +r<< hdfs://cafe-144:8020/accumulo/tables/+r/root_tablet
