---------------------------------------
Summary: Fix incremental compilation of parser module
Key: HIVE-25752
URL: https://issues.apache.org/jira/browse/HIVE-25752
Project: Hive
Issue Type: Bug
Reporter: Zoltan Haindrich
Assignee: Zoltan Haindrich
this issue doesn't happen all the time - but when it does its really annoying
the problem is that the antlr files are not regenerated; however the
"HiveParser.java Fix" is run regardless...which corrupts the java files after a
second run and causes compilation errors
