Re: Received metrics from unknown node

Thanks Ilya. No. Did not take a thread dump. Will do so if I observe this behaviour next time. Also how do I add monitoring for such nodes ? regards, eena. -- Sent from: http://apache-ignite-users.70518.x6.nabble.com/

Re: Ignite visor use

Ignite Visor starts daemon node inside to connect to the cluster, it doesn't matter cluster was started. All you need is to configure addresses of the cluster nodes in the config file, the same way as you do fo other nodes in the cluster. Evgenii пн, 8 июн. 2020 г. в 19:01, Prasad Bhalerao : > H

Re: CountDownLatch issue in Ignite 2.6 version

Can you pass host name to ignite visor?

Is there any way to pass the cluster address to ignitevisorcmd.sh on the command line or must it be set in the config.xml file used?

Re: Zookeeper discovery in mix environments.

Limit your env to two nodes. Try using --net=host for docker containers. If that works, limiting to use setLocalHost for TcpCommunicationSPI, and configure ZooKeeper to use address translation/or bind to a specific address. -- Sent from: http://apache-ignite-users.70518.x6.nabble.com/

Re: What does: Failed to send DHT near response mean?

Re: Countdown latch issue with 2.6.0

Hi, Have you tried to reproduce this behaviour with the latest release - 2.8.1? If I remember correctly, there were some fixes regarding the partition counters mismatches, for sample: https://issues.apache.org/jira/browse/IGNITE-10078 - Alex Shapkin -- Sent from: http://apache-ignite-users.

Re: Question regarding topology

Hello! It's not clear, whether the code snippet came from a client or a server. If it's a client, then I'd recommend you try sending the keys and additional data directly to a server node and perform the insertion directly on the node. The Compute API could be an option here [1] You might also wa

Re: Zookeeper discovery in mix environments.

I think the problem might also, be the client is running inside DC/OS with docker containers. When I check the network topology all connected aplication are reporting multiple addresses... Here is an example of a single client... Is it possible to tell it only bind to one or only use one?

Re: What does: Failed to send DHT near response mean?

It is. It seems to only happen when I scale the client. Just curious. is it possible that the client is bound to alot of address and causing communication issues??? When I look at the topology through ignite visor I see the client has multiple possible addresses. Is it possible to tell the client t

Re: Ignite memory memory-architecture with cache partitioned mode

I just wanted to highlight that there is the Partition Awareness feature available for thin clients. When enabled, a client will know to witch node a partition belongs and send a request directly to that node. [1] - https://apacheignite-net.readme.io/docs/thin-client#partition-awareness [2] - http

Re: embedded jetty & ignite

Clay, I assume embedding jetty as an ignite service, i.e., as an ignite server > node, is not desirable (still don't know the reason). Let's suppose that your cluster has 3 server/data nodes with application records distributed evenly - so that each node keeps ~33% of the whole data set. Next, i

Hi, By default, cache, that stores all atomic structures has only 1 backup, so, after losing all data for this certain latch, it recreates it. To change the default atomic configuration use IgniteConfiguration.setAtomicConfiguration. Evgenii сб, 6 июн. 2020 г. в 06:20, Akash Shinde : > *Issue:*

Re: Node is unable to join cluster because it has destroyed caches

Hello! It was disabled not just because of potential data loss but because the cache was resurrected on such start and could break cluster. Creating cache per operation and destroying afterwards is an anti-pattern, it can cause all sorts of issues and is better avoided. Regards, -- Ilya Kasnach

Re: Ignite SqlFieldQuery Unicode Characters Support

Hello! I have met an error like this one, and my recommendation is that on all nodes, client and server, you should set file.encoding to the same value (UTF-8 usually, however CJK multi-byte encodings should also work). Make sure all of your JVMs are launched with -Dfile.encoding=UTF-8. ignite.sh
