Parquet only calls converts for which it found the values. The missing values are not reported. The BlockBuilder must be appended with nulls for the missing values based on fieldIndex of the currently read value by Parquet.
…pass Ignore errors if the partitions have no corresponding valid hdfs path.
…gParquetColumns Append nulls for missing values in Parquet.
…d be reverted once prestodb#2863 is resolved.

Is it possible to use "RowType" instead of "struct"? Or may be use com.facebook.presto.hive.HiveType.java.
Same for the rest of the patch. Presto has RowType and struct is not used here directly IIRC.

Yeah, this part pained me pretty bad. I dug around for something more type safe but I missed HiveType. Refactoring.

LGTM, I saw some existing PR as well. We can start with this and wait for that to merge to master and released.. |
