[teiid-issues] [JBoss JIRA] (TEIID-2775) HIVE2: cannot run ORDER BY SQL without LIMIT

HIVE2: cannot run ORDER BY SQL without LIMIT --------------------------------------------- Key: TEIID-2775 URL: https://issues.jboss.org/browse/TEIID-2775 Project: Teiid Issue Type: Bug Components: Query Engine Affects Versions: 8.6 Environment: Teiid with HIVE2 Impala Reporter: Ivan Chan Assignee: Steven Hawkins Labels: teiid Fix For: 8.7 Cannot run SQL with order by, but without limit clause. If I run a sql like the following with HIVE2/ IMPALA: select "account_type" from "hive2DS"."accounts" group by "account_type" order by "account_type" Teiid would convert it to: SELECT g_0.account_type AS c_0 FROM accounts g_0 GROUP BY g_0.account_type ORDER BY c_0 And I will get the following exception: [3:51:04 PM] Natalia: org.teiid.jdbc.TeiidSQLException: Error trying to obtain metadata information for the tables that match %: TEIID30489 Unable to load metadata for VDB name Caused by: org.teiid.translator.jdbc.JDBCExecutionException: 0 TEIID11008:TEIID11004 Error executing statement(s): [Prepared Values: [] SQL: SELECT g_0.account_type AS c_0 FROM accounts g_0 GROUP BY g_0.account_type ORDER BY c_0] at org.teiid.translator.jdbc.JDBCQueryExecution.execute(JDBCQueryExecution.java:131) at org.teiid.dqp.internal.datamgr.ConnectorWorkItem.execute(ConnectorWorkItem.java:317) at org.teiid.dqp.internal.process.DataTierTupleSource.getResults(DataTierTupleSource.java:298) at org.teiid.dqp.internal.process.DataTierTupleSource$1.call(DataTierTupleSource.java:110) at org.teiid.dqp.internal.process.DataTierTupleSource$1.call(DataTierTupleSource.java:107) at java.util.concurrent.FutureTask$Sync.innerRun(FutureTask.java:334) at java.util.concurrent.FutureTask.run(FutureTask.java:166) at org.teiid.dqp.internal.process.FutureWork.run(FutureWork.java:58) at org.teiid.dqp.internal.process.DQPWorkContext.runInContext(DQPWorkContext.java:273) at org.teiid.dqp.internal.process.ThreadReuseExecutor$RunnableWrapper.run(ThreadReuseExecutor.java:119) at org.teiid.dqp.internal.process.ThreadReuseExecutor$3.run(ThreadReuseExecutor.java:214) ... 3 more Caused by: java.sql.SQLException: NotImplementedException: ORDER BY without LIMIT currently not supported at org.apache.hive.jdbc.Utils.verifySuccess(Utils.java:165) at org.apache.hive.jdbc.Utils.verifySuccessWithInfo(Utils.java:153) at org.apache.hive.jdbc.HiveStatement.execute(HiveStatement.java:198) at org.apache.hive.jdbc.HiveStatement.executeQuery(HiveStatement.java:300) at org.apache.hive.jdbc.HivePreparedStatement.executeQuery(HivePreparedStatement.java:106) at org.apache.tomcat.dbcp.dbcp.DelegatingPreparedStatement.executeQuery(DelegatingPreparedStatement.java:96) at org.apache.tomcat.dbcp.dbcp.DelegatingPreparedStatement.executeQuery(DelegatingPreparedStatement.java:96) at org.teiid.translator.jdbc.JDBCQueryExecution.execute(JDBCQueryExecution.java:123) ... 13 more Maybe you guys should consider to do order by in memory if LIMIT is not presented for HIVE2 IMPALA.
