Both CI jobs (C++ UT and Java UT) failed with the same error:

fatal error: velox/dwio/parquet/writer/WriterConfig.h: No such file or directory

This header was removed in the new Velox version (e603dc1). The WriterConfig struct (and its kParquetHiveConnectorWriteTimestampUnit constant) has been superseded by ParquetConfig in velox/dwio/parquet/common/ParquetConfig.h.

Fixed in commit Fix: replace removed WriterConfig.h with ParquetConfig.h in Init.cc by:

• Replacing #include <velox/dwio/parquet/writer/WriterConfig.h> → #include <velox/dwio/parquet/common/ParquetConfig.h>
• Replacing parquet::WriterConfig::kParquetHiveConnectorWriteTimestampUnit → "hive.parquet." + std::string(parquet::ParquetConfig::kWriterTimestampUnit) (both resolve to "hive.parquet.writer.timestamp-unit")
