Error reading parquet page in column

Error message

Error reading parquet page in column 

What it means

Wraps an IOException from ValuesReader.initFromPage while preparing a page's values reader in initDataReader: the page payload could not be initialized (truncated page, bad levels, unsupported layout). The catch converts it into a ParquetDecodingException naming the column.

Solutions

1. Verify the Parquet file is complete and uncorrupted in storage
2. Reproduce with the parquet-tools/verified reader to confirm page validity
3. Upgrade Presto if the page layout is valid but unsupported
