HUDI_FILESYSTEM_ERROR

Error message

Could not open file system for ${table}

What it means

HudiSplitManager.getFileSystem resolves an ExtendedFileSystem for the table's base path via HdfsEnvironment; any failure opening it (missing scheme support, bad credentials, unavailable naming authority) is wrapped in this PrestoException with the table path, aborting split generation for that table.

Solutions

1. Verify the table path URI and that a FileSystem implementation exists for its scheme
2. Check HDFS/S3 credentials and HdfsEnvironment configuration for the query user
3. Confirm the Hudi table location is reachable from all worker nodes
