Re: atlas webui is not accessible

Please follow the below mentioned steps whenever you face such issue: Cloudera Manager provides Atlas action option to initialize Atlas, which creates all the required backend resources HBase table, Solr collection and Kafka topics. Navigate to Atlas from the Cloudera Manager UI.  Under actions, the Initialize Atlas option appears. Initiate it; it will create the required resources.  Once done, verify the Altas UI.   If the issue is still not resolved, perform the following steps:   Login to Solr host and kinit with Solr principal as follows: # klist -kt /var/run/cloudera-scm-agent/process/XXX-solr-SOLR_SERVER/solr.keytab # kinit -kt /var/run/cloudera-scm-agent/process/XXX-solr-SOLR_SERVER/solr.keytab solr/host_name.principal.com@COE.CLOUDERA.COM Delete the  /solr  and  /solr-infra znodes  using Zookeeper client. Do the following: #/opt/cloudera/parcels/CDH/bin/zookeeper-client # ls / [solr, solr-infra] # deleteall /solr # deleteall /solr-infra # ls / (should not show any solr or solr-infra znodes) While performing the above steps, if you face error as " Authentication is not valid : /solr-infra/security " or " Node not empty :  /solr-infra/security/zkdtsm/ZKDTSMRoot ", kindly perform the following steps, or else skip to Step 3. Temporarily disable ACL by setting ' zookeeper.skipACL=yes ' in ZooKeeper's Java Advance configuration in Cloudera Manager Navigate to  Cloudera Manager  >  Zookeeper Service In Configuration, add ' -Dzookeeper.skipACL=yes ' to  Java Configuration Options for Zookeeper Server Restart ZooKeeper with the new configuration. Run the following: #export JAVA_HOME=/usr/java/jdk1.8.0 #/opt/cloudera/parcels/CDH-X.X.X/lib/solr/server/scripts/cloud-scripts/zkcli.sh -cmd clear -z "localhost:2181" /solr-infra  Repeat Step a Stop Solr service Execute  Initialize Solr  action from Solr service. Start Solr service Stop the Atlas service Execute  Initialize Atlas  action from Atlas service On Solr host, check if the following command returns the atlas_configs  instancedir : #solrctl instancedir --list #sample output _default atlas_configs managedTemplate If it returns  atlas_configs , skip this  create  command. If it does not return  atlas_configs , execute the following  create  command: #solrctl instancedir --create atlas_configs /opt/cloudera/parcels/CDH/etc/atlas/conf.dist/solr/ Check if the following command returns the  edge_index ,  fulltext_index , and  vertex_index  collections: #solrctl collection --list. #sample output vertex_index (5) edge_index (5) fulltext_index (5) If it does return the 3 collections above, skip the create commands below. If it does not return the 3 collections above, execute the following commands: #solrctl collection --create edge_index -c atlas_configs -s 1 -r 1 -m 1 #solrctl collection --create fulltext_index -c atlas_configs -s 1 -r 1 -m 1 #solrctl collection --create vertex_index -c atlas_configs -s 1 -r 1 -m 1 Start the Atlas service and bring up the UI.
