> Querying a partition in PostgreSQL fails when using JDO (with
> hive.metastore.try.direct.sql=false) . 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)

> {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)
