INVALID_SESSION_PROPERTY

INVALID_SESSION_PROPERTY

Error message

${MINIMUM_ASSIGNED_SPLIT_WEIGHT} must be > 0 and <= 1.0: ${value}

What it means

Session property validation for the Hudi connector: the minimum-assigned-split-weight session property is parsed and range-checked when building session properties; a value outside (0, 1.0] fails this check at connector setup, indicating an invalid numeric configuration for split weight distribution.

Solutions

1. Set the session property to a value in (0, 1.0], e.g. 0.05
2. Fix the default value in the Hudi connector configuration if it is out of range
