Ignite Cluster Issue on 2.7.6
Hi,
I have two module(Web and Engine) and want to share data b/w the modules , but when I run web and engine together , data is added to cache but is not available to either of modules.
below is my ignite config, which is same in both modules
config.setActiveOnStart(true);
config.setAutoActivationEnabled(true);
config.setIgniteHome(propertyReader.getProperty("spring.ignite.storage.path"));
config.setFailureHandler(new StopNodeOrHaltFailureHandler());
config.setDataStorageConfiguration(getDataStorageConfiguration());
config.setGridLogger(new JavaLogger(java.util.logging.Logger.getLogger(LOG.getClass().getCanonicalName())));
Ignite ignite = Ignition.start(config);
ignite.cluster().active(true);
All Caches created have below properties |
cache.setWriteSynchronizationMode(CacheWriteSynchronizationMode.FULL_ASYNC);
cache.setAtomicityMode(CacheAtomicityMode.TRANSACTIONAL);
cache.setCacheMode(CacheMode.REPLICATED);
cache.setGroupName("EngineGroup");
Both Modules are running on IP List : 127.0.0.1:47501,127.0.0.1:47502,127.0.0.1:47503,127.0.0.1:47504
Please suggest..

Hello!
Yes, you absolutely do need to add all nodes to BLT.
Do you have steps to reproduce that behavior? The exception suggests that
you have started a node, activated it, then shut it down, started other two
nodes and activated them separately. Then tried to start all 3 nodes as a
single cluster.

Hi,
Below are the logs
BaselineTopology of joining node (e6d542e7-cd73-4e57-90c1-b28da508c2c6) is not compatible with BaselineTopology in the cluster. Branching history of cluster BlT ([1016056908]) doesn't contain branching point hash of joining node BlT (510622971). Consider cleaning persistent storage of the node and adding it to the cluster again.

However, yes, all of your data nodes should be in baseline topology. Could you collect logs from your servers?

Hi,
Do you use cluster with persistence? After first actication all your data will be located on the first activated node.
In this case, you also should track your baseline.
https://www.gridgain.com/docs/latest/developers-guide/baseline-topology<https://apc01.safelinks.protection.outlook.com/?url=https%3A%2F%2Fwww.gridgain.com%2Fdocs%2Flatest%2Fdevelopers-guide%2Fbaseline-topology&data=04%7C01%7Cgurmehar.kalra%40hcl.com%7Cc975b5cbb3cf4d88ca6708d880984c02%7C189de737c93a4f5a8b686f4ca9941912%7C0%7C0%7C637400738885440196%7CUnknown%7CTWFpbGZsb3d8eyJWIjoiMC4wLjAwMDAiLCJQIjoiV2luMzIiLCJBTiI6Ik1haWwiLCJXVCI6Mn0%3D%7C1000&sdata=UIwjsZUzz2LQZfeSIFYL4zg3ybWNNEFfnBWXFm7TY8I%3D&reserved=0>
Baseline topology is a subset of nodes where you cache data located.
The recommendations are the following:
1)you should activate the cluster only when all server nodes were started
2)If the topology changes, you must either restore the failed nodes or reset to the base topology to trigger partition reassignment and rebalancing.
3)If some new node should contain the cache data then you should add this node to baseline topology:
using java code:

Do you use cluster with persistence? After first actication all your data will be located on the first activated node.
In this case, you also should track your baseline.

Baseline topology is a subset of nodes where you cache data located.
The recommendations are the following:
1)you should activate the cluster only when all server nodes were started
2)If the topology changes, you must either restore the failed nodes or reset to the base topology to trigger partition reassignment and rebalancing.
3)If some new node should contain the cache data then you should add this node to baseline topology:

Hi,
Did you remove the code with ignite.cluster().active(*true*); ?
However, yes, all of your data nodes should be in baseline topology.
Could you collect logs from your servers?

Hi,
I tried changes suggested by you , waited for nodes and then tried to start cluster , but only 1 node is joins cluster other node does not participates in cluster.
Do I have to add all nodes into BLT ?
