Not support other binary type

Error message

Not support other binary type: {}

What it means

Default arm of the binary-type switch in logicalTypeToOrcType: a binary-rooted logical type (e.g. BINARY vs VARBINARY variant) has no mapping branch to an ORC TypeDescription. The reported type is the LogicalType string that fell through the switch.

Solutions

1. Address the cause reported by the error message: Not support other binary type: the reported value
2. Verify the inputs, configuration values, and classpath/dependency setup related to this operation, then retry.

Example fix

Correct the condition described ("Not support other binary type: the reported value") and rerun the job or command.

When it happens

Trigger: Triggered at runtime when the operation fails because: Not support other binary type: the reported value.

Common situations: Commonly caused by misconfiguration, missing dependencies or files, unsupported types or operations, or invalid user input leading to: Not support other binary type: the reported value.
