Lefty Leverenz commented on HIVE-9482: -------------------------------------- Got your back, [~szehon] -- I changed the version number from 0.14.0 to 1.2.0 (probably a copy-&-paste error). * [hive.parquet.timestamp.skip.conversion | https://cwiki.apache.org/confluence/display/Hive/Configuration+Properties#ConfigurationProperties-hive.parquet.timestamp.skip.conversion] > Hive parquet timestamp compatibility > ------------------------------------ > > Key: HIVE-9482 > URL: https://issues.apache.org/jira/browse/HIVE-9482 > Project: Hive > Issue Type: Bug > Components: File Formats > Affects Versions: 0.15.0 > Reporter: Szehon Ho > Assignee: Szehon Ho > Fix For: 1.2.0 > > Attachments: HIVE-9482.2.patch, HIVE-9482.patch, HIVE-9482.patch, > parquet_external_time.parq > > > In current Hive implementation, timestamps are stored in UTC (converted from > current timezone), based on original parquet timestamp spec. > However, we find this is not compatibility with other tools, and after some > investigation it is not the way of the other file formats, or even some > databases (Hive Timestamp is more equivalent of 'timestamp without timezone' > datatype). > This is the first part of the fix, which will restore compatibility with > parquet-timestamp files generated by external tools by skipping conversion on > reading. > Later fix will change the write path to not convert, and stop the > read-conversion even for files written by Hive itself. -- This message was sent by Atlassian JIRA (v6.3.4#6332)
