i had to change some configurations in the ambari that inturn caused me to restart some of the services of the ambari. atlas was also one of them but when i try to restart it, it is failing continuously, it is asking for a restart again and again.
@pk reddy You'd need to start solr in order to start Atlas. Basically Atlas is dependent on 1) Kafka 2) Hbase & 3) Ambari Infra services and all of them should be up and running before you attempt to start Atlas.
The error below shows there is a problem with Solr,
Command failed, tries again (tries: 1) No live SolrServers available to handle this request org.apache.solr.client.solrj.SolrServerException: No live SolrServers available to handle this request
Can you stop and kill any Solr related process on the sandbox
# ps -ef | grep solr
If there any processes the
# kill -9 PID
Restart Solr it should reload/recreate the collections in zookeeper
Check the Atlas table
Log into hbase which is the default backend DB for Atlas as the hbase user
$ hbase shell
List the tables, make sure you have a similar output
hbase(main):003:0> list TABLE ATLAS_ENTITY_AUDIT_EVENTS atlas_titan 2 row(s) in 0.0690 seconds => ["ATLAS_ENTITY_AUDIT_EVENTS", "atlas_titan"]
The restart Atlas
All should be okay
Nice to know it was resolved.
