Snowflake Connection Does Not Work Anymore

Issue

I am experiencing an issue with my snowflake database. I have been able to access it for weeks, but today I am receiving the error message "JDBC driver internal error: exception creating result java.lang.NoClassDefFoundError: Could not initialize class net.snowflake.client.jdbc.internal.apache.arrow.memory.RootAllocator at net.snowflake.client.jdbc.SnowflakeResultSetSerializableV1.create(SnowflakeResultSetSerializableV1.java:577)." I am unsure how to resolve this issue and am seeking assistance.

Resolution

To resolve this issue, follow these steps:

  1. Update the Snowflake JDBC Driver:
    • Ensure that you're using the latest version of the Snowflake JDBC driver, which likely contains the necessary fixes for this issue.
    • Download and install the latest version from the Snowflake documentation.
  2. Restart Your Application:
    • After updating the JDBC driver, restart your application or service to apply the changes.
  3. Monitor for Fixes:
    • If the issue persists, check for any updates or known issues in the Snowflake community or documentation to see if additional steps are needed.

By updating the driver, you should resolve the class initialization issue related to the RootAllocator.
