Timeout failures when using semantic-link for spark sql

Hi dbeavon3,

Thank you for reaching out in Microsoft Community Forum.

Since your primary tenant is in West US but your Fabric capacity (where the Spark pool runs) is in North Central US, some requests may still be routed through the tenant region, leading to timeouts.

java.net.SocketTimeoutException error related to SynapseML when running Spark notebooks in a scenario where your tenant and capacity are in different regions. This cross-region configuration can sometimes lead to network latency issues, especially with services like SynapseML.

please follow below steps to resolve the error;

1.Run ping or traceroute to check network delays and make sure no firewall or proxy restrictions are affecting connections.

2. Scale up Spark pool resources for better performance.

3.Identify any authentication or connection failures and Break large queries into smaller steps to improve performance.

Please continue using Microsoft community forum.
