ParquetFileWriter in invalid state after network outage in end(metadata)

Comienza con parquet-hadoop/src/main/java/org/apache/parquet/hadoop/ParquetFileWriter.java e inspecciona las transiciones de estado alrededor de end(metadata) y las operaciones que fallan. Reproduce el fallo usando TestParquetWriter.testParquetWriterWithFailingIO y sigue el estado ENDED reportado. El trabajo está terminado cuando una carga fallida no deja al writer en un estado no válido al intentar close de nuevo.

Describe the bug, including details regarding any error messages, version, and platform.

Related to apache/iceberg#13508, possibly to #1971,

We're using parquet-java 1.15.2 as part of iceberg, uploading data to S3. The data is flushed to storage in configurable intervals.

Description

If a short network interruption happens exactly while writing and uploading files, the ParquetFileWriter is already transitioned into the state ENDED, even though the file has not been written successfully.
Another call to close the (iceberg-) writer results in an exception of the ParquetFileWriter, being in an invalid state.

Possible Solution

Every time the internal field state is updated, it is done in the very beginning of a method, which is too early. If later in the method's code an exception is thrown, not all logic has been executed successfully, leaving the writer in an invalid state.
But simply moving the transition in state to the end of the method could result in executing the code multiple times, if a retry-mechanism calls the method multiple times - that must also be avoided.
One possibility would be to introduce more internal states. This would allow to track the state of the writer in more detail, which again makes it more resilient to retries.
