Hi.

I installed druid 0.14.1 cluster and now I have an error on my Data server for historical process:

Now I don't know how to change this localIp (127.0.0.1) to my coordinator server Ip.

@AzamAhmadloo You can add hosts in your cluster. 104.xxx.xxx.xx1 overlord 104.xxx.xxx.xx2 coordinator

@AzamAhmadloo overlord and coordinator log file

AzamAhmadloo commented 5 years ago

@w3z4y4

Where are log files? The previous log was log for run command. Do you need this log?

w3z4y4 commented 5 years ago

@AzamAhmadloo You can use these command to start Druid~

java `cat conf/druid/coordinator/jvm.config | xargs` -cp conf/druid/_common:conf/druid/coordinator:lib/* org.apache.druid.cli.Main server coordinator > coordinator.log  2>&1 &
java `cat conf/druid/overlord/jvm.config | xargs` -cp conf/druid/_common:conf/druid/overlord:lib/* org.apache.druid.cli.Main server overlord >overlord.log  2>&1 &

My error on master server fixed. Now my master server see middlemanager server correctly. I added druid.worker.ip=192.168.0.0 to conf/druid/middlemanager/runtime.properties

The error remains on historical server:

WARN [main] org.apache.druid.discovery.DruidLeaderClient - Request[http://localhost:8081/druid/coordinator/v1/lookups/config/__default?detailed=true] failed. org.jboss.netty.channel.ChannelException: Faulty channel in resource pool java.net.ConnectException: Connection refused: localhost/127.0.0.1:8081

How to connect to coordinator server from historical server?

How did you fix this issue?

That was my first view of druid. You should know zookeeper is incredibly important in your cluster and all your nodes should configure correctly about this. This is the tip.
