@Kumar Tg I have the same setup on a single node cluster, I think your atlas.graph.index.search.solr.zookeeper-url should be changed to infra-solr. I logged in my zookeeper to check the parameters. The vertex_index is accessible in infra-solr $ bin/zkCli.sh ..... [zk: localhost:2181(CONNECTED) 0] ls / [hive, registry, cluster, controller, brokers, zookeeper, infra-solr, hbase-unsecure, kafka-acl, kafka-acl-changes, admin, isr_change_notification, templeton-hadoop, hiveserver2, controller_epoch, druid, rmstore, hbase-secure, ambari-metrics-cluster, consumers, config] [zk: localhost:2181(CONNECTED) 2] ls /infra-solr/collections [vertex_index, edge_index, fulltext_index] Parameter to change atlas.graph.index.search.solr.zookeeper-url = ZOOKEEPER_HOSTNAME:2181/infra-solr Then try restarting Atlas.

@sbx_hadoop A lab environment or Dev should NEVER be in archive log mode !!! What version is your Oracle database maybe some old hacks could still work. Do you have command line access to the oracle server.? If so can you locate the initxxx.ora or spfile? usually in $ORACLE_HOME\dbs and check your db name to ensure you log on the correct database Linux boxes usually have many databases. Check if you can switch user to the user running the database process ! This should give you the oracle user $ ps -ef | grep oracle or ps -ef | grep pmon Run the below to set the correct variable from values you get from above export ORACLE_HOME=/path/to/oracle_home export ORACLE_SID=xxxx Then as root switch to this user so have to have all the oracle variables in your path, You MUST log on as sysdba that's the only internal user allowed to access the database in such situations. eg if the owner owner/user is oradba # su - oradba Now you can invoke sqlplus $sqlplus /nolog SQL>conn / as sysdba SQL> archive log list; Check the Archive destination and delete all the logs SQL> shutdown immediate SQL> startup mount SQL> alter database noarchivelog; SQL> alter database open; SQL> archive log list; You should see Automatic archival Disabled Now you can proceed with restarting your Ambari server ...

@Sedat Kestepe Can you delete the entry in zookeeper and restart # locate zkCli.sh /usr/hdp/2.x.x.x/zookeeper/bin/zkCli.sh # /usr/hdp/2.x.x.x/zookeeper/bin/zkCli.sh [zk: localhost:2181(CONNECTED) 8] ls /hadoop-ha/ You should see something like [zk: localhost:2181(CONNECTED) 8] ls /hadoop-ha/xxxxx Delete the Hdfs ha config entry [zk: localhost:2181(CONNECTED) 1] rmr /hadoop-ha Validate that there is no hadoop-ha entry, [zk: localhost:2181(CONNECTED) 2] ls / Then restart the all components HDFS service. This will create a new ZNode with correct lock(of Failover controller). Please let me know if that helped. ... View more

@Michael Bronson Can you instead do a # grep namenodes /etc/hadoop/conf/hdfs-site.xml Then get the values of the parameter dfs.ha.namenodes.xxxx Please let me know ... View more

@Michael Bronson Did you run your command as root instead of hdfs [root@master01 hdfs]# hdfs haadmin -getServiceState master02 Illegal argument: Unable to determine service address for namenode 'master02' To validate master02 can you check the names of the namenodes in hdfs-site.xml ... View more

Because its down ! ... View more

@Michael Bronson The commands failed because the namenodes were already dead. The ls /hadoop-ha/hdfsha is now responding correctly .Election issue means the zookeeper can't put the namenode in Active and standby they all remain in a Can you restart the name nodes and get their status and quickly run with one command $ hdfs haadmin -getAllServiceState Check the health hdfs haadmin -checkHealth There is a difference in your command and the one I posted ,please use the correct serviceId $ hdfs haadmin -transitionToActive <serviceId> --forceactive and yours $ hdfs haadmin -transitionToActive master01 --forceactiv transitionToActive: ...
