(Updated Dec. 7, 2015, 10:16 a.m.) Review request for hive. Changes ------- Added Sergey's reflection code that makes Hive to be able to downgrade the DN JAR. Repository: hive-git Description ------- Bugs in DataNucleus and MySQL Connector! Any Hive user will potentially hit the problem. My SELECT query got incorrect results because JDOQLQuery.compileQueryFull swallowed the fatal datastore exception when it called RDBMSQueryUtils.getStatementForCandidates. This is a bug in RDBMSQueryUtils.getStatementForCandidates or its caller(s).
