从10.2.0.4数据库将数据导入到11.2.0.3 rac，日志文件中有如下错误信息：

ORA-01427: single-row subquery returns more than one row

从这里可以看出是在执行TABLE_STATISTICS的时候因为数据类型和导入数据不匹配,导致impdp job终止.

解决办法
参考文档:[ID 878626.1]
1.如果数据已经expdp导出,建议在导入的时候屏蔽掉统计信息导入EXCLUDE=STATISTICS,导入后使用DBMS_STATS 重新收集统计信息

impdp lbs/lbs directory=a1 dumpfile=lbs_20140310.dmp  logfile=lbs20140310.log TABLE_EXISTS_ACTION=append parallel=5  cluster=n  EXCLUDE=STATISTICS

导入完成后重新检查，发现导入成功。
