Following is the reproduce example: {code} create table partition_test_multilevel (key string, value string) partitioned by (level1 string, level2 string, level3 string); insert overwrite table partition_test_multilevel partition(level1='1111', level2='111', level3='11') select key, value from srcpart tablesample (11 rows); insert overwrite table partition_test_multilevel partition(level1='1111', level2='222', level3='11') select key, value from srcpart tablesample (15 rows); insert overwrite table partition_test_multilevel partition(level1='1111', level2='333', level3='11') select key, value from srcpart tablesample (20 rows); select level1, level2, level3, count(*) from partition_test_multilevel where level2 <= '222' group by level1, level2, level3; {code} The query fails with following error: {code} Caused by: org.apache.hadoop.hive.ql.parse.SemanticException: MetaException(message:Invocation of method "substring" on "StringExpression" requires argument 1 of type "NumericExpression") at org.apache.hadoop.hive.ql.optimizer.ppr.PartitionPruner.getPartitionsFromServer(PartitionPruner.java:392) at org.apache.hadoop.hive.ql.optimizer.ppr.PartitionPruner.prune(PartitionPruner.java:215) at org.apache.hadoop.hive.ql.optimizer.ppr.PartitionPruner.prune(PartitionPruner.java:139) at org.apache.hadoop.hive.ql.parse.ParseContext.getPrunedPartitions(ParseContext.java:619) at org.apache.hadoop.hive.ql.optimizer.pcr.PcrOpProcFactory$FilterPCR.process(PcrOpProcFactory.java:110) ... 21 more {code} It is because the JDO pushdown filter generated for a query having inequality/between partition predicate uses DN indexOf function which is not working properly with postgresql (see http://www.datanucleus.org/servlet/jira/browse/NUCRDBMS-840) -- This message was sent by Atlassian JIRA (v6.3.4#6332)
