I am still using Corda 1.0 version. when i try to redeploy nodes with existing data, getting below error while start-up but able to access the nodes . If i clear the data and redeploy the nodes, i didn't face these error message.

This looks like the Artemis failed to connect to the node which means the node fails to start.
You should look at the log and if there are any other previous Corda node started which occupy the node.
If there are any legacy Corda nodes that have not been killed, try ps -ef |grep java to see if there is any other java still alive. Especially look for the port number and check if they are overlapped

When I try to look up for this kind of problem, most are because they were using a proxy, but I don't. I get this error on my git bash:

I'm following the guide on nextjs.org. I thought it was due to my bad connection, but when I try it another time, I still get the same error.
My Node.js is at v14.17.5.
I am new to Oracle, installed oracle SQL developer but each time I try to connect, I get the error:
Status: Failure -Test failed: IO Error: The Network Adapter could not
establish the connection
and the oracleTNSlistener service turns off on its own. Each time I start the service, it turns off immediately on its own.
I am trying to run corda on multiple nodes. As per this thread - https://github.com/corda/corda/issues/39, I have modifed the node.conf files and started the nodes. (BankA and Notary on machineA, BankB and BankCorda on MachineB) and started all four of them. Till node startup everything is fine.
When I try to run this - gradlew samples:trader-demo:runBuyer from machine A, I get the following error on NodeA - unknown peer - BankOfCorda
and the
Notary - [ERROR] 2018-06-01T12:37:22,766 [Node thread] StateMachineManager - Unknown peer C=UK,L=London,OU=corda,O=R3,CN=BankOfCorda in SessionInit(initiatorSessionId=6217119355343956857, flowName=net.corda.flows.NotaryFlow$Client, firstPayload=SignRequest(tx=SignedTransaction(txBits=[14010…], sigs=[[…]], id=xxx)))
Am I doing something wrong?
This is because you have messages queued up in your nodes' message queues when you stop them. After changing the nodes' names and restarting the nodes, the message queues can't find the desired recipients on the network.
You can fix this by deleting each node's artemis folder.
I'm trying to get Spark, and SparkR, running on a small EC2 cluster using the provided scripts and directions. Whenever I ask for an operation that would require computation on an RDD (e.g., collect(), reduce()), I get the error logged below. Workers do appear to startup correctly -- if I only parallelize, I see the workers running via the master's web ui.
The error I get is similar to the one in Intermittent Timeout Exception using Spark and I've been through all of the solutions there (modifying the conf file for URL's, disabling the firewall, etc.), no luck.
Here is the error log, thank you in advance for your help:

This was ultimately resolved by a combination of
- Updates to SparkR, which have resolved a number of serialization issues.
- Recognizing that the Spark-ec2 scripts require that the control node and master node be the same machine.
and
- Replacing calls to parallelize() with distributing and then loading the data by hadoop.
I am writing an intro to SparkR for R programmers that I hope will help people with things like this in the future.
Got an EndpointWriter error:
14/10/30 23:12:29 ERROR EndpointWriter: AssociationError [akka.tcp://sparkWorker#node001:35249] -> [akka.tcp://sparkExecutor#node001:7088]: Error [Association failed with [akka.tcp://sparkExecutor#node001:7088]] [

Caused by: akka.remote.transport.netty.NettyTransport$$anonfun$associate$1$$anon$2: Connection refused: node001/10.69.144.56:7088
the node001 and 10.69.144.56 are both the node itself. my understanding is that akka was trying to connect to a port in local but got rejected. The executor port was fixed to be '7087'.
Thanks for your help!
The usual reason for connection refused is that there is nothing listening on the port. If the port that executor is listening on is 7087, akka is trying to make a connection to port 7088 and there's probably nothing listening there. Check your code or configuration to see if you got 7088 instead of 7087.
