Sergey Shelukhin commented on HIVE-12986: ----------------------------------------- IIRC that's because antlr3 and 4 are basically different libraries with different package sets and APIs, so there's no problem with using them simultaneously, and it's a lot of work to upgrade the antlr3-using parts. I may be misremembering though... (there's a mailing list thread somewhere) > make sure Hive uses Antlr runtime version compatible with HPLSQL > ---------------------------------------------------------------- > > Key: HIVE-12986 > URL: https://issues.apache.org/jira/browse/HIVE-12986 > Project: Hive > Issue Type: Improvement > Reporter: Sergey Shelukhin > Priority: Blocker > > HPLSQL requires Antlr-runtime 4.5, however Hive uses an older version. If > there are no obstacles to this, Hive should simply be upgraded to the newer > version -- This message was sent by Atlassian JIRA (v6.3.4#6332)
