Storm UI Internal Server Error for remote cluster

[Chun Yuen Lim]

I'm following

I try to configuring Apache Storm remote cluster in Amazon Web Services and
I face the error below in my Storm UI:

org.apache.thrift7.transport.TTransportException:
java.net.ConnectException: Connection refused
at org.apache.thrift7.transport.TSocket.open(TSocket.java:183)

at backtype.storm.ui.core$fn__8260.invoke(core.clj:844)

This is my storm.yaml file for my master node at 10.0.0.230:

########### These MUST be filled in for a storm configuration
storm.zookeeper.servers:
- "10.0.0.230"
# - "localhost"

Below is my storm.yaml file for slave node at 10.0.0.79:

# nimbus.childopts: "-Xmx512m"
# supervisor.childopts: "-Xmx256m"

Below is my zoo.cfg file for master node:

tickTime=2000
initLimit=10
syncLimit=5
dataDir=/home/ubuntu/zookeeper-data
dataLogDir=/home/ubuntu/zookeeper/log/data_log
clientPort=2181
server.1=10.0.0.230:2888:3888
autopurge.snapRetainCount=3
autopurge.purgeInterval=24

I had use zkServer.sh start, storm nimbus & storm ui in master node; storm
supervisor in slave node. The myid for master node is 1 & the myid for
slave node is 2.

What is the cause of error? how to solve it?

hi, you nimbus.host is listening on localhost nimbus.host: "127.0.0.1" .
Storm UI makes calls to nimbus to get storm cluster and topology info.
Make sure your nimbus and nimbus thrift port is reachable from storm ui
host. -Harsha

My zookeeper is reside in the same node with nimbus, so I just use
127.0.0.1. However, I solve the issue already, I don't know why, but the
problem solved when I delete the
dataLogDir=/home/ubuntu/*zookeeper/log/data_log
*in my zoo.cfg
