This is a WIP. The PR has been taken over from nongli (see https://github.com/apache/spark/pull/10420). I have removed some additional dead code, and fixed a few issues which were caused by the fact that the inlined Hive parser is newer than the Hive parser we currently use in Spark. I am submitting this PR in order to get some feedback and testing done. There is quite a bit of work to do: - [ ] Get it to pass jenkins build/test. - [ ] Aknowledge Hive-project for using their parser. - [ ] Refactorings between HiveQl and the java classes. - [ ] Create our own ASTNode and integrate the current implicit extentions. - [ ] Move remaining ```SemanticAnalyzer``` and ```ParseUtils``` functionality to ```HiveQl```. - [ ] Removing Hive dependencies from the parser. This will require some edits in the grammar files. - [ ] Introduce our own context which needs to contain a ```TokenRewriteStream```. - [ ] Add ```useSQL11ReservedKeywordsForIdentifier``` and ```allowQuotedId``` to the catalyst or sql configuration. - [ ] Remove ```HiveConf``` from grammar files &HiveQl, and pass in our own configuration. - [ ] Moving the parser into sql/core. cc nongli rxin Author: Herman van Hovell <hvanhovell@questtec.nl> Author: Nong Li <nong@databricks.com> Author: Nong Li <nongli@gmail.com> Closes #10509 from hvanhovell/SPARK-12362. |
