In fabric ensemble setup, one fuse server has joined successfully using fabric:join command.
After that if we run container-list command it throws below error and in cli it displayed "error executing command: java.lang.nullpointerexception".
(log file)
io.fabric8.api.FabricException: org.apache.zookeeper.KeeperException$NoNodeException: KeeperErrorCode = NoNode for /fabric/authentication/crypt/algorithm

I am trying to install kubeadm and for this i am trying to create vagrant environment i clone this link "https://github.com/kodekloudhub/certified-kubernetes-administrator-course" to my server and then run the command "vagrant up". I take this error.I am using Ubuntu 20.04.5 LTS

There was an error while executing VBoxManage, a CLI used by Vagrant
for controlling VirtualBox. The command and stderr is shown below.
Command: ["hostonlyif", "create"]
Stderr: 0%...
Progress state: NS_ERROR_FAILURE
VBoxManage: error: Failed to create the host-only adapter
VBoxManage: error: VBoxNetAdpCtl: Error while adding new interface: failed to open /dev/vboxnetctl: No such file or directory
VBoxManage: error: Details: code NS_ERROR_FAILURE (0x80004005), component HostNetworkInterfaceWrap, interface IHostNetworkInterface
VBoxManage: error: Context: "RTEXITCODE handleCreate(HandlerArg*)" at line 95 of file VBoxManageHostonly.cpp
i want to create vagrant environment
This problem was solved by downgrading the "VirtualBox" version. Try to install version 6.38.
I am running a sample pipeline and my environment is this.
python "SaiStudy - Apache-Beam-Spark.py" --runner=PortableRunner --job_endpoint=192.168.99.102:8099
My Spark is running on a Docker Container and I can see that the JobService is running at 8099.
I am getting the following error:
grpc._channel._MultiThreadedRendezvous: <_MultiThreadedRendezvous of RPC that terminated with:
status = StatusCode.UNAVAILABLE

debug_error_string = "{"created":"#1603539936.536000000","description":"Failed to pick subchannel","file":"src/core/ext/filters/client_channel/client_chann

When I curl to ip:port, I can see the following error from the docker logs

Help Please.
Please find instruction here how to setup PortableRunner for Spark:
https://beam.apache.org/documentation/runners/spark/
Basically you need to setup additional Docker container (as described) which acts as runner between Beam (in any language) and Spark.
You connect Beam to runner, and runner to the Spark.
I'm getting below error while starting the Kafka-Server on Windows machine. I've downloaded Scala 2.11 - kafka_2.11-2.1.0.tgz from the link: https://kafka.apache.org/downloads and I did the following steps:
Go to config folder in Apache Kafka (C:\Apache-Kafka\kafka_2.11-2.1.0\config) and edit “server.properties” using any text editor.
Find log.dirs and repelace after “=/tmp/kafka-logs” to C:\Apache-Kafka\kafka_2.11-2.1.0\kafka-logs.
Now simply start the server:
>kafka-server-start.bat C:\Apache-Kafka\kafka_2.11-2.1.0\config

Note: I've already setup Apache Zookeeper on my Windows machine and it's running on port 2181.
I run the command using run as administrator.
Try this after kafka-server-start.bat
use this: ....\config\server.properties with slash between 2 dots

In general we must not use C: drive to store kafka-logs. You can try using the drive other than the C: for storing Kafka logs. It must work.
Change the property log.dirs={Drive other than C:}/tmp/kafka-logs present in KafkaHome/config/server.properties.
