Read path for int64 (HIVE-21050, HIVE-21215) is committed to master and write path (HIVE-21216) should be committed soon. > Hive parquet timestamp compatibility, part 2 > -------------------------------------------- > > Key: HIVE-22006 > URL: https://issues.apache.org/jira/browse/HIVE-22006 > Project: Hive > Issue Type: Bug > Affects Versions: All Versions > Reporter: H. Vetinari > Priority: Major > > The interaction between HIVE / IMPALA / SPARK writing timestamps is a major > source of headaches in every scenario where such interaction cannot be > avoided. > HIVE-9482 added hive.parquet.timestamp.skip.conversion, which *only* affects > the *reading* of timestamps. > It formulates the next steps as: > > Later fix will change the write path to not convert, and stop the > > read-conversion even for files written by Hive itself. > At the very least, HIVE needs a switch to also turn off the conversion on > writes. That would at least allow a setup where all three of HIVE / IMPALA / > SPARK can be configured not to convert on read/write, and can hence safely > work on the same data -- This message was sent by Atlassian Jira (v8.3.4#803005)
