What causes "Failed to dispose the savepoint '{}'." in apache/flink?

Read the cause: EOF vs. illegal values narrows truncation vs. corruption

Failed to dispose the savepoint '{}'.

Error message

Failed to dispose the savepoint '{}'.

What it means

Thrown from NestedPrimitiveColumnReader.initDataReader when dataColumn.initFromPage(pageValueCount, in) fails with IOException — the nested column's values reader could not initialize over the page body (after repetition/definition levels were consumed). It wraps the real cause (truncation, malformed values payload) with column context.

Solutions

Read the cause: EOF vs. illegal values narrows truncation vs. corruption
Verify file integrity and re-read a clean copy; cross-check with `parquet-tools dump`
If reproducible in reference readers, the file is malformed — regenerate at the source
If only Flink fails, minimize the file and report to Flink (parquet component)

Defensive patterns

Strategy: try-catch

Try / catch

try {
    nestedReader.readAndNewVector(...);
} catch (IOException e) {
    // 'Could not read page in col %s.' — inspect root cause; deterministic per file
    throw new CorruptParquetFileException(path, descriptor, e);
}

Prevention

Checksum-verify file transfers; atomic-publish finished files only
Cross-validate suspicious files with parquet-tools before escalation
Include column path and row-group ordinal in surrounding diagnostics

When it happens

Trigger: Page body shorter than the values reader expects for pageValueCount values; invalid value payloads for the encoding; stream position corruption after level decoding; decompression anomalies.

Common situations: Truncated/corrupt files; writers with page-sizing bugs for nested columns; files damaged in storage or transfer.
