我正在做一个项目，我们使用cdh嵌入式postgresql。几天前我们发现了两件事。sqoop创建的表（配置单元表）失败了，从配置单元创建动态分区表也失败了。
错误如下
第一天：

Loading data to table raw_store.user_pdp_visits partition (view_date=null)
Failed with exception MetaException(message:javax.jdo.JDODataStoreException: Insert of object "org.apache.hadoop.hive.metastore.model.MPartition@67d2b6c" using statemen
t "INSERT INTO "PARTITIONS" ("PART_ID","PART_NAME","TBL_ID","LAST_ACCESS_TIME","CREATE_TIME","SD_ID") VALUES (?,?,?,?,?,?)" failed : ERROR: duplicate key value violates
 unique constraint "PARTITIONS_pkey"
  Detail: Key ("PART_ID")=(481) already exists.
NestedThrowables:

FAILED: Execution Error, return code 1 from org.apache.hadoop.hive.ql.exec.MoveTask

之后：

Moving data to: hdfs://hadoop01.snapdeal.com:8020/tmp/hive-hdfs/hive_2014-05-27_09-00-19_755_4383214683545337621-1/-ext-10000/view_date=2014-05-26

如果有人能给出同样的解决方案，那就太好了。
