Can you share these 2 Atlas logs in /var/log/atlas

• application.log
  
• gc-worker.log.0.current
  

Did it work before is your cluster kerberized ? What OS?

I don't see anything significant in the logs you attached. Can you enable DEBUG.

From Ambari UI -->Atlas--Config-->Advanced atlas-log4j

Uncomment the below line and restart Atlas

 <!-- uncomment this block to generate performance traces 
<appender name="perf_appender"> 
<param name="File" value="{{log_dir}}/atlas_perf.log" /> 
<param name="datePattern" value="'.'yyyy-MM-dd" /> 
<param name="append" value="true" /> 
<layout class="org.apache.log4j.PatternLayout"> 
<param name="ConversionPattern" value="%d|%t|%m%n" /> 
</layout> 
</appender> 
<logger name="org.apache.atlas.perf" additivity="false"> 
<level value="debug" /> 
<appender-ref ref="perf_appender" /> 
</logger> 
--> 

This will generate logs with $atlas_perf.log upload those files

Connect to zookeeper and check if the hbase table are available

# /usr/hdp/current/zookeeper-client/bin/zkCli.sh 

Then on the zk CLI list the hbase tables

[zk: localhost:2181(CONNECTED) 0] ls /hbase-secure/table 
[ATLAS_ENTITY_AUDIT_EVENTS, hbase:meta, atlas_titan, hbase:namespace, hbase:acl]
