Spark connection to slave on standalone cluster - apache-spark

So I have my master node on my Mac and I can check on the webserver my master url as spark://private_ip_address:7077. Then I try to connect a slave node on a remote server.
So I run start-slaves.sh from the master and it creates a log on the remote server. So I assume that the ssh connection is ok. However the connection with the master is not possible as shown by the log content.

I would be so grateful for some help to understand why this does not connect properly and show on the webserver the slave node.

Docker-Flink: TaskManagers can't find JobManager when in different nodes in Docker Swarm

This happens even when the nodes are in the same subnet.
I am using the Docker-Flink project in:
https://github.com/apache/flink/tree/master/flink-contrib/docker-flink
I am creating the services with the following commands:
docker network create -d overlay overlay
docker service create --name jobmanager --env JOB_MANAGER_RPC_ADDRESS=jobmanager -p 8081:8081 --network overlay --constraint 'node.hostname == ubuntu-swarm-manager' flink jobmanager
docker service create --name taskmanager --env JOB_MANAGER_RPC_ADDRESS=jobmanager --network overlay --constraint 'node.hostname != ubuntu-swarm-manager' flink taskmanager
This is the error I get:
- Trying to register at JobManager akka.tcp://flink#jobmanager:6123/ user/jobmanager (attempt 4, timeout: 4000 milliseconds)
These are my environment configurations:
node: ubuntu-swarm-master Azure VM Standard D4s v3 (4 vcpus, 16 GB
memory) Docker version 17.03.1-ce, build c6d412e
node: azure-swarm-worker-1 Azure VM Standard D2 v2 Promo (2 vcpus, 7
GB memory) Docker version 17.09.0-ce, build afdb6d4
Flink: using image 1.3.2-hadoop2-scala_2.10
This is from the log of the container running TaskManager:

Why can't the TaskManagers talk to JobManager? I wonder if there's some configuration missing. Any help will be much appreciated. Thank you very much!

The issue was related to an unhealthy node, therefore it was not able to assign the task. The solution was to increase the yarn maximum disk utilization percentage in yarn-site.xml because my disk was at 97% used :
<property>
<name>yarn.nodemanager.disk-health-checker.max-disk-utilization-per-disk-percentage</name>
<value>99</value>
</property>

Is there something wrong with the configuration?

I had faced same issue.
Posting the answer so that it might help others.
As the log suggests, the property "cassandra.override_decommission" should be overridden.
start cassandra with the syntax:
cassandra -Dcassandra.override_decommission=true
This should add the node back to the cluster.

Setting Spark master ip #

I have a Spark workers which can't connect to its master because of an IP issue.
On the start-all.sh on the master (which name is 'pl'), I get the following on the slave log :
16/02/12 21:28:35 INFO WorkerWebUI: Started WorkerWebUI at http://192.168.0.38:8081
16/02/12 21:28:35 INFO Worker: Connecting to master pl:7077...
16/02/12 21:28:35 WARN Worker: Failed to connect to master pl:7077
java.io.IOException: Failed to connect to pl/192.168.0.39:7077
Here is my /etc/hosts file :
$ cat /etc/hosts
127.0.0.1 localhost
127.0.1.1 wk
192.168.0.39 pl
# The following lines are desirable for IPv6 capable hosts
::1 localhost ip6-localhost ip6-loopback
ff02::1 ip6-allnodes
ff02::2 ip6-allrouters
It seems like spark worker is confused between the master names and IP address...How should I set up this ?
Another question is : looking at the master's logs, it seems that the master is listening on another port (7078) than the one the worker is trying to reach (7077) because of a failure to start on the 1st port tried.

But what is strange is that the local worker logs as if successusfully connected to the local master on port :

16/02/12 21:28:38 INFO Worker: Successfully registered with master spark://pl:7077

You can try running netstat -pna | grep 7077 (needs root privileges) on the master to see what process is blocking the port.
Maybe you have another driver instance running. If this is a Java process blocking the port you can use jps to find out more about it.

cqlsh not connecting when configuring a two node cluster on windows server

I am trying to configure a two node cluster with cassandra in windows r2 2008 So i installed cassandra community version in one server (10.xxx.0.1,10.xxx.0.2) And then I stopped the service and then edited the configuraton.yaml file in the conf folder.
The changes are:
cluster_name
commented the num_tokens
gave the tokens in initial_token,
seeds as 10.xxx.0.1,10.xxx.0.2,
listen_addresses are their respective ip addresses which are 10.xxx.0.1,10.xxx.0.2,
rpc_addresses are same as listen_address,
endpointsnitch as gossip
I also changed the cassandra rackdc.properties file to dc=DC1 rack=RAC1.
and changed the cassandra-env file - uncommented: JVM_OPTS="$JVM_OPTS -Djava.rmi.server.hostname=10.xxx.0.1
I then saved and started back the service and ran nodetool status and got
Datacenter: DC1
Status=Up/Down

and opened the cqlsh, but it is not connecting. Below is the error:
