Bug created in JIRA as HIVE-10316 -----Message d'origine----- De : Gopal Vijayaraghavan [mailto:[email protected]] De la part de Gopal Vijayaraghavan Envoyé : Monday, April 13, 2015 11:46 PM À : [email protected] Objet : Re: same query works with TEXTFILE and fails with ORC
> I¹m getting an error in Hive when executing a query on a table in ORC >format. This is not an ORC bug, this looks like a vectorization issue. Can you try comparing both query plans (³explain <query>²) for the Execution mode: vectorized markers? TextFile queries are not vectorized today, since you cannot find if any column is marked as isRepeating=true in a row-major format. > SELECT CONCAT(TO_DATE(datetime), '-'), SUM(gpa) FROM students_orc >GROUP BY CONCAT(TO_DATE(datetime), '-Œ); ... > Caused by: org.apache.hadoop.hive.ql.metadata.HiveException: >Unsuported vector output type: StringGroup > at >org.apache.hadoop.hive.ql.exec.vector.VectorColumnSetInfo.addKey(Vector >Col >umnSetInfo.java:139) > at >org.apache.hadoop.hive.ql.exec.vector.VectorHashKeyWrapperBatch.compile >Key >WrapperBatch(VectorHashKeyWrapperBatch.java:521) > at >org.apache.hadoop.hive.ql.exec.vector.VectorGroupByOperator.initializeO >p(V >ectorGroupByOperator.java:786) The correct fix would be to handle this query pattern for vectorization (or automatically disable vectorization, like it has to do for Unions). Can you log a bug on Apache JIRA against the correct version of hive which threw this error up?
