Hi Denis
What would make an ignite node a

via an ignite service deployed on
each node and I am not setting the
client mode anywhere. The code
sets the jdbc connection to local
and tries to execute a sql code on
the node in some interval. By the
way, I didn't know one could
deploy a service on client nodes.
Do I need to explicitly mark a
node as a server node when
deploying a service?

Hi Denis -- How would I detect that rebalancing started, or finished? Do I need to listen to the rebalancing events and abort the task in case a rebalancing has started? thanks.

Hi Narges, Then just send a task to a required node. If the cluster topology changes while the task was running you can re-submit it to ensure the result is accurate. - Denis On Fri, Oct 30, 2020 at 2:16 PM narges saleh wrote: > Hi Denis, > > My problem with using affinity call/run is that I have to have the key in > order to run it.

Re: Execution of local SqlFieldsQuery on client node disallowed
Narges, Also, keep in mind that if a local query is executed over a partitioned table and it happens that partitions rebalancing starts, the local query might return a wrong result (if partitions the query was executed over were rebalanced to another node during the query execution time). To address this: 1. Execute the local query inside of an affinityCall/Run function ( https://ignite.apache.org/docs/latest/distributed-computing/collocated-computations#colocating-by-key). Those functions don't let partitions be evicted until the function execution completes. 2. Don't use the local queries, let the Ignite SQL engine to run standard queries, and to take care of possible optimizations. - Denis On Mon, Oct 26, 2020 at 8:50 AM Ilya Kasnacheev wrote: > Hello! > > You are using an Ignite Thick Client driver.

Hello! You are using an Ignite Thick Client driver. As its name implies, it will start a local client node and then connect to it, without the option of doing local queries.

Hello Ilya Yes, it happens all the time. It seems ignite forces the "client" establishing the jdbc connection into a client mode, even if I set client=false. The sample code and config are attached.

Re: Execution of local SqlFieldsQuery on client node disallowed
Denis -- Just checked. I do specify my services to be deployed on server nodes only. Why would ignite think that I am running my code on a client node?

Re: Execution of local SqlFieldsQuery on client node disallowed
Hi Denis What would make an ignite node a client node? The code is invoked via an ignite service deployed on each node and I am not setting the client mode anywhere. The code sets the jdbc connection to local and tries to execute a sql code on the node in some interval. By the way, I didn't know one could deploy a service on client nodes. Do I need to explicitly mark a node as a server node when deploying a service? thanks On Thu, Oct 22, 2020 at 9:42 PM Denis Magda wrote: > The error message says you're attempting to run the query on a client > node.

Re: Execution of local SqlFieldsQuery on client node disallowed
The error message says you're attempting to run the query on a client node. If that's the case (if the service is deployed on the client node), then the local flag has no effect because client nodes don't keep your data locally but rather consume it from servers. - Denis On Thu, Oct 22, 2020 at 6:26 PM narges saleh wrote: > Hi All, > I am trying to execute a sql query via a JDBC connection on the service > node (the query is run via a service), but I am getting *Execution of > local SqlFieldsQuery on client node disallowed.* > *The JDBC connection has the option local=true as I want to run the query > on the data on the local node only.* > *Any idea why I am getting this error?* > > *thanks.* >
Execution of local SqlFieldsQuery on client node disallowed
Hi All, I am trying to execute a sql query via a JDBC connection on the service node (the query is run via a service), but I am getting *Execution of local SqlFieldsQuery on client node disallowed.* *The JDBC connection has the option local=true as I want to run the query on the data on the local node only.* *Any idea why I am getting this error?* *thanks.*
