Miles Granger commented on SPARK-44988:
---------------------------------------
[~fanjia]that "worked" for me, but then of course need to cast the resulting
bigint to a timestamp, which I feel is error prone. Would be nice if spark
supported timestamp[ns] though.
> Parquet INT64 (TIMESTAMP(NANOS,false)) throwing Illegal Parquet type

>
> Key: SPARK-44988
> URL: https://issues.apache.org/jira/browse/SPARK-44988
> Project: Spark
> Issue Type: Bug
> Components: SQL
> Affects Versions: 3.4.0, 3.4.1
> Reporter: Flavio Odas
> Priority: Critical
>
> This bug seems similar to https://issues.apache.org/jira/browse/SPARK-40819,
> except that it's a problem with INT64 (TIMESTAMP(NANOS,false)), instead of
> INT64 (TIMESTAMP(NANOS,true)).
> The error happens whenever I'm trying to read:
> {code:java}
> org.apache.spark.sql.AnalysisException: Illegal Parquet type: INT64
> (TIMESTAMP(NANOS,false)).
