Hi, Based on master branch refreshed today, I issued 'git clean -fdx' first.
Then this command: build/mvn clean -Phive -Phive-thriftserver -Pyarn -Phadoop-2.6 -Dhadoop.version=2.7.0 package -DskipTests I got the following error: scala> sql("explain codegen select 'a' as a group by 1").head org.apache.spark.sql.catalyst.parser.ParseException: extraneous input 'codegen' expecting {'(', 'SELECT', 'FROM', 'ADD', 'DESC', 'WITH', 'VALUES', 'CREATE', 'TABLE', 'INSERT', 'DELETE', 'DESCRIBE', 'EXPLAIN', 'LOGICAL', 'SHOW', 'USE', 'DROP', 'ALTER', 'MAP', 'SET', 'START', 'COMMIT', 'ROLLBACK', 'REDUCE', 'EXTENDED', 'REFRESH', 'CLEAR', 'CACHE', 'UNCACHE', 'FORMATTED', 'DFS', 'TRUNCATE', 'ANALYZE', 'REVOKE', 'GRANT', 'LOCK', 'UNLOCK', 'MSCK', 'EXPORT', 'IMPORT', 'LOAD'}(line 1, pos 8) == SQL == explain codegen select 'a' as a group by 1 --------^^^ Can someone shed light ? Thanks
