########## format/spec.md: ########## @@ -913,9 +913,9 @@ Lists must use the [3-level representation](https://github.com/apache/parquet-fo Notes: -1. ORC's [TimestampColumnVector](https://orc.apache.org/api/hive-storage-api/org/apache/hadoop/hive/ql/exec/vector/TimestampColumnVector.html) comprises of a time field (milliseconds since epoch) and a nanos field (nanoseconds within the second). Hence the milliseconds within the second are reported twice; once in the time field and again in the nanos field. The read adapter should only use milliseconds within the second from one of these fields. The write adapter should also report milliseconds within the second twice; once in the time field and again in the nanos field. ORC writer is expected to correctly consider millis information from one of the fields. More details at https://issues.apache.org/jira/browse/ORC-546 Review Comment: Explanation: "comprise of" is apparently not gramatically correct, it's actually the other way : "a time field and nano field comprise ORC's TimestampColumnVector". This was from my editor's auto-correct which suggested to just use 'consists of' instead. -- This is an automated message from the Apache Git Service.
