Subject [jira] [Created] (HIVE-3814) Cannot drop partitions on table when using Oracle metastore
Date Tue, 18 Dec 2012 03:08:24 GMT

----------------------------------------

             Summary: Cannot drop partitions on table when using Oracle metastore
                 Key: HIVE-3814
                 URL: https://issues.apache.org/jira/browse/HIVE-3814
             Project: Hive
          Issue Type: Bug
          Components: SQL
    Affects Versions: 0.10.0
         Environment: Oracle 11g r2
            Reporter: Deepesh Khandelwal
            Priority: Critical


Create a table with a partition. Try to drop the partition or the table containing the partition.
Following error is seen:
FAILED: Error in metadata: MetaException(message:javax.jdo.JDODataStoreException: Error executing
JDOQL query "SELECT 'org.apache.hadoop.hive.metastore.model.MPartitionColumnStatistics' AS
NUCLEUS_TYPE,THIS.AVG_COL_LEN,THIS."COLUMN_NAME",THIS.COLUMN_TYPE,THIS.DB_NAME,THIS.DOUBLE_HIGH_VALUE,THIS.DOUBLE_LOW_VALUE,THIS.LAST_ANALYZED,THIS.LONG_HIGH_VALUE,THIS.LONG_LOW_VALUE,THIS.MAX_COL_LEN,THIS.NUM_DISTINCTS,THIS.NUM_FALSES,THIS.NUM_NULLS,THIS.NUM_TRUES,THIS.PARTITION_NAME,THIS."TABLE_NAME",THIS.CS_ID
FROM PART_COL_STATS THIS LEFT OUTER JOIN PARTITIONS THIS_PARTITION_PARTITION_NAME ON THIS.PART_ID
= THIS_PARTITION_PARTITION_NAME.PART_ID WHERE THIS_PARTITION_PARTITION_NAME.PART_NAME = ?
AND THIS.DB_NAME = ? AND THIS."TABLE_NAME" = ?" : ORA-00904: "THIS"."PARTITION_NAME": invalid
identifier

The problem here is that the column "PARTITION_NAME" that the query is referring to in table
"PART_COL_STATS" is non-existent. Looking at the hive schema scripts for mysql & derby,
this should be "PARTITION_NAME". Postgres also suffers from the same problem.
