[jira] [Commented] (DRILL-4373) Drill and Hive have incompatible timestamp representations in parquet

    [ https://issues.apache.org/jira/browse/DRILL-4373?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=15538934#comment-15538934 ] 

Khurram Faraaz commented on DRILL-4373:
---------------------------------------

The description says Drill & Hive have incompatible timestamp representations in parquet. Ideally we want parquet files generated by Drill to be compatible/usable on Hive, Impala, Spark etc, and vice versa.

> I created a parquet file with a timestamp type using Drill. Now if I define a hive table on top of the parquet file and use "timestamp" as the column type, drill fails to read the hive table through the hive storage plugin
