RE: Java to .NET interop

Hi Pavel, Thanks for the quick reply. I have not explicitly tried to only deploy the service classes without the entity classes into the java classpath on the .NET side. Our entity and service classes are packaged into the same jar. I won’t investigate this further, as its just as much of an

Ignite Events Remote Filter

cache closed or destroyed issue

Hi, We are facing an issue with Ignite cache where it throws an IllegalArgumentException with Cache closed or destroyed. I have two java applications that start the ignite cache in an embedded mode. The cache instances form a cache cluster with the help of zookeeper plugin for discovery. The

Re: Custom SecurityCredentialsProvider and SecurityCredentials

Hi Frank, Sorry for late response. SecurityCredentialsProvider is not used in Ignite code because Ignite doesn't provide any implementations of SecurityProcessor out of the box. If you want to make your cluster secure, you need to implement it and configure as a part of your own custom plugin.

Re: Ignite 2.3 - replicated cache lost data after restart cluster nodes with persistence enabled

Dmitriy, I don’t see why a result of a simple query such as “select count(*) from t;” should be different if a rebalancing is in progress or after a cluster restart. Ignite’s SQL engine claims that its fault-tolerant and returns a consistent result set all the times unless a partition loss

Re: Ignite 2.3 - replicated cache lost data after restart cluster nodes with persistence enabled

Hi Denis It seems to me that this is not a bug for my scenario, because the data was not loaded within the same transaction using transactional cache. In this case it is ok that cache data is rebalanced according to partition update counters,isn't it? I suppose in this case the data was not lost

Re: Ignite in embeded mode in Spark running in dynamic mode

Ranjit, You can use it with Yarn or without Yarn. The point is that Ignite cluster is independent from Spark cluster, i.e. runs in separate processes. -Val -- Sent from: http://apache-ignite-users.70518.x6.nabble.com/

Re: ComputeGrid API in C++

Ignite node = Ignition::Start("node1"); The first argument to Start() needs to be an xml file. Are there any specific properties that need to be set in the xml for this case? If I call Start(cfg, "node1"), it just launches node1 within the same process as the application. In the below diagram,

Re: Node and cluster maintenance best practice

Follow the same process if you have the persistence enabled. Deactivate the cluster, terminate the nodes and do the upgrade. If you want to upgrade nodes in a rolling upgrade fashion then look for features provided enterprise products built on top of Ignite. — Denis > On Oct 23, 2017, at 6:57

Re: ComputeGrid API in C++

Hi, You don't have to modify platforms/cpp/ignite/src/ignite.cpp. Why won't you modify your code, where you start the node? I mean, in *your application code* write something like this: Ignite node = Ignition::Start("node1"); IgniteBinding binding = node.GetBinding();

Hi Igor Shouldn't be a problem, given that the source code is there. I just want to make sure that I am doing it the right way. Currently, I have modified the main() method in platforms/cpp/ignite/src/ignite.cpp and added these two lines: IgniteBinding binding = ignite.GetBinding();

You need to have the same code on all C++ nodes to be able to execute it remotely. In other words, you need to register classes you want to invoke remotely on all three nodes. Is that a problem for you? Best Regards, Igor On Wed, Oct 25, 2017 at 6:35 PM, asingh wrote: >
