-----------------------------------
Labels: pull-request-available (was: )
> [PYTHON] Raise structured PySparkRuntimeError for PermissionError and other
> OSError subclasses when reading Protobuf descriptor file
> ------------------------------------------------------------------------------------------------------------------------------------
>
> Key: SPARK-59872
> URL: https://issues.apache.org/jira/browse/SPARK-59872
> Project: Spark
> Issue Type: Improvement
> Components: PySpark
> Affects Versions: 4.4.0
> Reporter: Brij Raj Kishore
> Priority: Minor
> Labels: pull-request-available
>
> Follow-up to [SPARK-43847|https://issues.apache.org/jira/browse/SPARK-43847]
> ([PR #56174|https://github.com/apache/spark/pull/56174]).
> h3. Problem
> {{_read_descriptor_set_file()}} in {{pyspark.sql.protobuf.functions}}
> currently maps only {{FileNotFoundError}} to the structured
> {{PROTOBUF_DESCRIPTOR_FILE_NOT_FOUND}} error condition. Other {{OSError}}
> subclasses ({{PermissionError}}, {{IsADirectoryError}}, etc.) propagate as
> raw Python exceptions, inconsistent with Spark's structured error approach.
> h3. Solution
> Add a new {{PROTOBUF_DESCRIPTOR_FILE_READ_FAILED}} error condition and map
> remaining {{OSError}} subclasses to a structured {{PySparkRuntimeError}},
> consistent with the approach taken for {{FileNotFoundError}} in SPARK-43847.
> Note: the Scala side currently maps these cases to
> {{CANNOT_PARSE_PROTOBUF_DESCRIPTOR}}, which nchammas noted is not ideal — a
> dedicated Python-specific error condition is more accurate.
