Kafka Failed To Send Producer Request With Correlation Id
other. Join them; it only takes a minute: Sign up Kafka - Unable to send a message to a remote server using Java up vote 5 down vote favorite 2 I'm trying to create a Kafka cluster to send messages to a remote control. I have configured everything as described here. I am running this on a Linux advertised.host.name kafka red hat machine, and it works fine using the shell. After writing the java code as described in the quick start tutorial on my windows machine, I have received the following error: ...

I have also tried to run the jar in a different Linux machine, and still received the same error. Changing the address to localhost and running the java code as a jar in the machine where the kafka is installed works. I believe it something with the configuration, but I couldn't find it. java linux apache-kafka share|improve this question asked Jan 26 '15 at 7:58 Candroid 7631920 add a comment| 1 Answer 1 active oldest votes up vote 16 down vote accepted In your kafka se

Enabling CORS for... » Remote TaskFlows/Remote Region - For Advanced Reusability in Oracle ADF By Shay Shmeltzer-Oracle on Nov 17, 2015 A new feature in Oracle ADF 12.2.1 is Remote TaskFlows (or Remote Regions) - this allows one application to https://blogs.oracle.com/shay/entry/remote_taskflows_remote_region_even have regions inside it that are populated from taskflows that are running as part of another application. Initially some of you might be a bit confused - "wasn't this something that we were able to do https://qnalist.com/questions/4782701/how-produce-to-remote-kafka-cluster-over-ssh-tunneling with ADF libraries already? We could just package a taskflow from one app as an ADF library and use that library in the other application". The slight distinction here is that the library approach had the failed to taskflow running as part of your consuming application. Remote task flows on the other hand have the taskflow running as part of the other application and don't require the creation of a library. As a result they also don't require an ADF library update when the taskflow changes- the minute the changes are deployed on the remote server, your application will get the new version. One way of thinking about remote taskflows is failed to send as adding a "portal" like functionality to your ADF app - allowing one app to display parts of another app leveraging the other app resources for executing any logic. Here is a quick video demoing how to configure and run this. The URLs you'll need for creating the remote region resource connection are: http://yourserver:port/your-context-root/rtfquery and http://yourserver:port/your-context-root/rr Note that there are some limitation on the type and functionality of taskflows that can be exposed as remote taskflows. And there are other things to consider such as security and session timeout settings. So have a read through the remote region documentation before you start leveraging this feature. A couple of notes. 1. In the currently available 12.2.1 version of JDeveloper from OTN, there is a slight bug that will prevent you from creating the connection to the remote task flow - there is a patch available for this from Oracle Support - request the patch for bug 22132843or22093099. 2. At my OOW session about new features I mentioned that remote task flows are loaded in parallel, that is actually still not the case, while we started work on this capability - it didn't made it into 12.2.1. So remote task flows behave like other task flows and load in sequential way right now. Category: JDeveloper Tags: regions taskflows
produce to Remote Kafka Cluster over SSH Tunneling.Configuration is below.- Kafka cluster in DataCenter(each machine has Grobal IP Address).Firewall allows only ssh port(22).ex) 192.168.100.100- Kafka producer exists out of DataCenter.ex) 172.16.0.100I tried produce over SSH Tunneling.Producer successed getting meta data from brokers.But meta data is Address which producer can't access directry.Detail is below.1. Ssh connect producer machine to DataCenter.172.16.0.100 > 192.168.100.100:222. Create SSH Tunnel over ssh connection.172.16.0.100's localhost:19092 to 192.168.100.100:9092(Kafka receive port).3. Producer connect to localhost:19092.Producer get metadata from brokers(192.168.100.100:9092).4.
