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.*

Hello,
You can use events:
https://ignite.apache.org/releases/latest/javadoc/org/apache/ignite/events/CacheRebalancingEvent.html
But in this case, you should wait until the rebalancing of all caches is
completed.
Also you can use the web console tool:
https://apacheignite-tools.readme.io/v2.8.0/docs
And the last option is to use the following property:
https://www.gridgain.com/sdk/ee/latest/javadoc/org/apache/ignite/IgniteSystemProperties.html#IGNITE_WAIT_FOR_BACKUPS_ON_SHUTDOWN
With the current setting, your node, which was properly stopped, will
not be stopped until there are backups in the cluster.
BR,

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.

Hi Denis,
My problem with using affinity call/run is that I have to have the key in
order to run it. I just want to run a function on the data on the current
node, without knowing the key. Is there anyway to do this and also
guard against partition rebalancing?

Re: Execution of local SqlFieldsQuery on client node disallowed
Posted by Denis Magda <dm...@apache.org>.
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.

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.
You need to use Ignite Thin JDBC driver: jdbc:ignite:thin://<server ip>
Then you can do 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. The question is how
do I force JDBC connections from a server node.
thanks.

Hello!
Does this happen every time? If so, do you have a reproducer for the issue?

Denis -- Just checked. I do specify my services to be deployed on server

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

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.
